Today, perspectives of using the picosecond and femtosecond pulses for biological tissue analysis are limited with several problems. One of them is an absence of direct sources of radiation in water transparency windows, e.g. 1.3 and 1.7 microns. There are several techniques that can produce that kind of radiation. In order to generate it we used synchronous pump and stimulated Raman scattering in a phosphosilicate fiber inside an external cavity. Our work presents the experimental and numerical modeling results for 1.3 micron Raman dissipative soliton generation in an all-fiber system. Additionally, attempts of pulse synchronous amplification are reported.
