Abstract: A method for addressing in idual laser pulses in high repetition frequency systems using an intracavity optical chopper and novel electronic timing system is reported. This “pulse on command” capability is shown to enable free running and both subharmonic pulse rate and burst mode operation of a high power, high pulse frequency copper vapor laser while maintaining a fixed output pulse energy. We demonstrate that this technique can be used to improve feature finish when laser micromachining metal.

Compact 2.5-W 10-kHz Nd : YLF-pumped dye laser
Publisher: Optica Publishing Group
Date: 20-03-2002
DOI: 10.1364/AO.41.001714
Abstract: A 10-kHz pulse repetition frequency dye laser, end pumped by a Nd:YLF laser, is reported. This laser was tunable from 590 to 655 nm, and up to 2.55 W of output power was obtained at the 609-nm peak tuning wavelength. By inserting an etalon into the dye laser cavity and frequency doubling using a beta-barium borate crystal, we obtained up to 125 mW of 308-nm single-etalon-mode output, which shows potential for the performance of airborne measurements of tropospheric hydroxyl radical concentrations.
Method for determination of the volume of material ejected as molten droplets during visible nanosecond ablation
Publisher: Optica Publishing Group
Date: 10-12-2004
DOI: 10.1364/AO.43.006473
Abstract: A novel method is presented for determining the volume of molten material ejected from a substrate as a result of visible pulsed-laser ablation. A 100-microm-wide pulsed-laser light sheet (tau approximately 5 ns, lambda = 532 nm) was used in conjunction with a CCD camera to provide high-speed cross-sectional images of single-pulse ablation of aluminum with a visible nanosecond laser source. Computational analysis of the two-dimensional gray-scale images was used to determine the total volume of material ejected from the substrate in the form of molten droplets. Ablation with dual-wavelength (511- and 578-nm) pulses of 30-ns duration was characterized under various fluence conditions (0-25 J cm(-2)), allowing a quantitative threshold for explosive melt ejection in aluminum to be established at approximately 10 J cm(-2). The temporal evolution of the ejected material showed that, for an incident fluence of approximately 40 J cm(-2), molten-droplet ejection commenced at approximately 400 ns and ceased after approximately 2 micros.
All-solid-state parametric Raman anti-Stokes laser at 508 nm
Publisher: Optica Publishing Group
Date: 09-01-2009
DOI: 10.1364/OE.17.000810
Abstract: We report a parametric anti-Stokes Raman laser using potassium gadolinium tungstate, generating output chiefly at the first anti-Stokes at 508 nm. The compact 4.5 cm long device is pumped by a Q-switched 532 nm laser and uses an off-axis Stokes resonator to provide non-collinear phase matching between the pump and the generated Stokes and anti-Stokes fields. Anti-Stokes output energies up 0.27 mJ were obtained at a conversion efficiency from the pump of 0.46%. Second- and third-order anti-Stokes lines at 486 nm and 465 nm were also observed.
Temperature-dependent polarization effects in Ce:LiLuF
Publisher: Optica Publishing Group
Date: 20-08-2001
DOI: 10.1364/AO.40.004326
Abstract: We report on tuned-laser, pump-probe-gain, and fluorescence yield studies of the effect that crystal temperature plays on the polarized emission characteristics of Ce:LiLuF. It was found that varsigma-polarized emission at the 327-nm fluorescence spectra peak is characterized by smaller laser pulse buildup times, higher small-signal gains, and smaller output powers than the pi-polarized 327-nm emission. We concluded that excited-state absorption (ESA) (and the resultant formation of color centers) is more severe for varsigma-polarized emission than for pi-polarized emission in this spectral region. We postulate that the enhancement in laser performance and crystal fluorescence observed with crystal cooling is due to narrowing of the ESA absorption band that reduces the probability of ESA and color-center formation.

Generation of sub-100 fs ultraviolet pulses from a Kerr-lens mode-locked Ce:LiCAF laser
Publisher: Optica Publishing Group
Date: 13-09-2021
DOI: 10.1364/AO.434823
Abstract: We report the direct generation of mode-locked pulses as short as 91 fs from the broad-bandwidth gain medium of L i C a A l F 6 (Ce:LiCAF) by combining Kerr-lens mode locking with synchronous pumping. The latter of these schemes, and the broad bandwidth of Ce:LiCAF, resulted in dispersion tuning of wavelength via cavity length in the spectral region of 290 nm this mechanism facilitated a practical means of estimating intra-cavity dispersion, which was compensated for using a Brewster’s-cut prism pair. The pulse duration was measured via split-beam asynchronous cross-correlation using a Ti:sapphire reference laser and a known time reference. From the Ce:LiCAF laser cavity, output powers of 110 mW and a 9% slope efficiency were achieved.
Mode-locked deep ultraviolet Ce:LiCAF laser

Date: 26-05-2009
DOI: 10.1364/OL.34.001660
Abstract: We report mode-locked operation of a synchronously pumped Ce:LiCAF oscillator. The laser operated in the deep UV with output radiation centered at 291 nm and a pulse duration of 6 ps. The maximum output power measured was 52 mW, with 13% slope efficiency. The Ce:LiCAF crystal has a gain bandwidth capable of supporting few-femtosecond pulses, and so our results demonstrate the potential to form a new class of ultrafast lasers operating directly at deep UV wavelengths.

Abstract: We report, for what we believe to be the first time, a Ce:LiCAF laser pumped by ultraviolet radiation obtained by sum-frequency mixing of the green and the yellow output from a copper-vapor laser. The 7-kHz pulse repetition frequency free-lasing Ce:LiCAF laser yielded a maximum output power of 530 mW, with a slope efficiency of 32%, from a pump power of 1.9 W. With a single prism tunability from 280.5 to 316 nm was achieved.

Wedged etalon tuning for miniature and monolithic lasers

Date: 10-07-2006
DOI: 10.1364/OL.31.002296
Abstract: We present an architecture permitting broad tuning of monolithic microchip lasers by using a wedged etalon. Full tuning from 282 to 314 nm is demonstrated by using a miniature Ce:LiCAF laser design, where tuning is achieved by translating the entire Ce laser cavity relative to the pump beam. The application of this technique to a range of microchip lasers will lead to extremely robust tunable monolithic lasers.

DOI: 10.1364/AO.420855
Abstract: By combining integral field spectroscopy with extreme adaptive optics, we are now able to resolve objects close to the diffraction limit of large telescopes, exploring new science cases. We introduce an integral field unit designed to couple light with a minimal plate scale from the SCExAO facility at NIR wavelengths to a single-mode spectrograph. The integral field unit has a 3D-printed micro-lens array on top of a custom single-mode multi-core fiber, to optimize the coupling of light into the fiber cores. We demonstrate the potential of the instrument via initial results from the first on-sky runs at the 8.2 m Subaru Telescope with a spectrograph using off-the-shelf optics, allowing for rapid development with low cost.

Laser-based volumetric flow visualization by digital color imaging of a spectrally coded volume

DOI: 10.1063/1.2825462
Abstract: We present the framework for volumetric laser-based flow visualization instrumentation using a spectrally coded volume to achieve three-component three-dimensional particle velocimetry. By delivering light from a frequency doubled Nd:YAG laser with an optical fiber, we exploit stimulated Raman scattering within the fiber to generate a continuum spanning the visible spectrum from 500to850nm. We shape and disperse the continuum light to illuminate a measurement volume of 20×10×4mm3, in which light sheets of differing spectral properties overlap to form an unambiguous color variation along the depth direction. Using a digital color camera we obtain images of particle fields in this volume. We extract the full spatial distribution of particles with depth inferred from particle color. This paper provides a proof of principle of this instrument, examining the spatial distribution of a static field and a spray field of water droplets ejected by the nozzle of an airbrush.

Abstract: Ultraviolet (UV) miniature cerium fluoride lasers have been demonstrated using a low cost, frequency-quadrupled microchip Nd:YAG pump laser. The use of miniature laser cavities was shown to significantly improve the laser performance in the low pump power region. We have achieved slope efficiencies up to 70% and pump thresholds as low as 100 nJ. Continuous tuning from 306 nm to 338 nm was achieved using a Brewster angle prism.

Kilohertz pulse repetition frequency slab Ti:sapphire lasers with high average power (10 W)
Publisher: Optica Publishing Group
Date: 20-11-1999
DOI: 10.1364/AO.38.006904
Abstract: High-average-power broadband 780-nm slab Ti:sapphire lasers, pumped by a kilohertz pulse repetition frequency copper vapor laser (CVL), were demonstrated. These lasers are designed for damage-free power scaling when pumped by CVL's configured for maximum output power (of order 100 W) but with poor beam quality (M(2) approximately 300). A simple Brewster-angled slab laser side pumped by a CVL produced 10-W average power (1.25-mJ pulses at 8 kHz) with 4.2-ns FWHM pulse duration at an absolute efficiency of 15% (68-W pump power). Thermal lensing in the Brewster slab laser resulted in multitransverse mode output, and pump absorption was limited to 72% by the maximum doping level for commercially available Ti:sapphire (0.25%). A slab laser with a multiply folded zigzag path was therefore designed and implemented that produced high-beam-quality (TEM(00)-mode) output when operated with cryogenic cooling and provided a longer absorption path for the pump. Excessive scattering of the Ti:sapphire beam at the crystal surfaces limited the efficiency of operation for the zigzag laser, but fluorescence diagnostic techniques, gain measurement, and modeling suggest that efficient power extraction (>15 W TEM(00), >23% efficiency) from this laser would be possible for crystals with an optical quality surface polish.
Analysis of Deep Learning Techniques for Dental Informatics: A Systematic Literature Review
Publisher: MDPI AG
Date: 28-09-2022
DOI: 10.3390/HEALTHCARE10101892
Abstract: Within the ever-growing healthcare industry, dental informatics is a burgeoning field of study. One of the major obstacles to the health care system’s transformation is obtaining knowledge and insightful data from complex, high-dimensional, and erse sources. Modern biomedical research, for instance, has seen an increase in the use of complex, heterogeneous, poorly documented, and generally unstructured electronic health records, imaging, sensor data, and text. There were still certain restrictions even after many current techniques were used to extract more robust and useful elements from the data for analysis. New effective paradigms for building end-to-end learning models from complex data are provided by the most recent deep learning technology breakthroughs. Therefore, the current study aims to examine the most recent research on the use of deep learning techniques for dental informatics problems and recommend creating comprehensive and meaningful interpretable structures that might benefit the healthcare industry. We also draw attention to some drawbacks and the need for better technique development and provide new perspectives about this exciting new development in the field.
