This project aims to develop advanced technologies to optically levitate macroscopic (millimetre-sized) objects and nanoscopic (atomically thin) materials. Levitation platforms built by the investigatory team are based on the resonantly amplified radiation pressure of laser beams. This new type of optical levitation can provide ultimate isolation of the systems from external noise, making them extremely responsive to subtle environmental changes. These platforms could be turned into sharp instruments for measuring metrological variables of interest and probing new physics. Quantum optical techniques could be developed to optimise the sensitivity of levitated systems to levels that allow the exploration of quantum and gravitational physics.Read moreRead less

Seeing the light: high-power visible-light generation using silicate fibre. Unlike their near-infrared counterparts, visible-light-emitting lasers are inefficient and complicated, impacting their broader deployment in industry, medicine, and telecommunications. To address this, we will create a new class of laser and amplifier based on an entirely new doped silicate glass fibre that will display low background loss and resilience to photodegradation from high-power visible light.

The project aims to generate and investigate several novel families of self-stabilising optical pulses by using a unique fibre laser we recently devised. By developing the associated theoretical models, the team will transform conceptual and experimental knowledge of nonlinear physics, providing deep insights into fibre lasers and the pulses they can emit. The expected outcomes are a complete understanding of entirely novel families of optical pulses, and of the degree to which the energy required to generate these pulses can be reduced. Reducing this energy means that these pulses can perform the same function at lower power, which will enable the emergence of new applications that will play powerful roles in the 21st-century economy.Read moreRead less
