Raman-Free Switching between Dissipative Soliton Resonances in Fiber Figure of Eight Laser

Summary form only given. Dissipative soliton (DS) is a well-known concept attracting substantial practical and fundamental interest [1]. DS generation is often accompanied by the DS resonance effect, when energy of soliton is growing with increasing its temporal duration. Following resonance leads to peak power clamping effect and narrowing optical spectrum that potentially limits a performance of fiber laser [2]. Also, in the area of high-energy solitons strong limitation on peak power is affected by stimulated Raman scattering saturating peak power of a soliton [3]. Here we demonstrate that fiber 8 -figure fiber laser with two amplifying fibers provides efficient Raman -free switching between dissipative soliton resonances. This leads to opportunity significantly (by a factor of 6) increase peak power of the output solitons.
