Dissipative soliton resonance in fiber lasers

Due to the quantization of the pulse energy in fiber lasers, it is challenging to find effective ways to increase the pulse energy directly from a fiber laser oscillator. One efficient and promising technique is based on the dissipative soliton resonance (DSR) effect which is a special solution of the nonlinear propagation equation manifesting as a square-wave pulse with a constant peak power and increasing pulse energy and duration when the pumping power increases. Experimentally, DSR is favored with the use of long or ultra-long cavities and has been observed in many optical configurations with various rare-earth doped fibers. In this paper we give a comprehensive review of the DSR in fiber lasers. Theoretical background is considered as well as the most relevant experimental results.
