Dissipative soliton resonances and their applications. Many branches of science and technology, such as precise eye surgery, biological cell machinery, painless dentistry, optical data storage, material micro-machining and laser fusion, rely heavily on high power femtosecond pulse laser oscillators that deliver the necessary power, in a very short time, to nanometer scale targets within a tissue or a material.

Many branches of science and technology, such as precise eye surgery, biological cell machinery, painless dentistry, optical data storage, material micro-machining and laser fusion, rely heavily on high power femtosecond pulse laser oscillators that deliver the necessary power, in a very short time, to nanometer scale targets within a tissue or a material. A further increase in the power of a pulse and a decrease in its duration, combined with a reduction in complexity and price can be achieved, but this advance depends strongly on the theory of dissipative solitons, and particularly on the idea of soliton resonances. Novel ideas developed within this project will put new productive tools in the hands of doctors, biologists and physicists.Read moreRead less
