In this study, pulse shrinkage of dissipative soliton resonance (DSR) pulses in a fiber laser is investigated. It is found that when the gain continues to increase, the DSR pulses undergo shrinkage, contrary to the expected pulse broadening. Additionally, pulse shrinkage and period doubling can be observed by changing the initial settings.
Dissipative soliton resonance (DSR) is a promising operation regime in fiber lasers where unlimited pulse energy boost is expected. However, several phenomena classified as anti-DSR performance were reported recently. Here pulse shrinkage of DSR pulses is investigated in a fiber laser. By setting a central-wavelength drifting Gaussian filter, after DSR performance of pulse broadening with increasing gain, the pulse shrinkage occurs when the gain continues to increase. A central-wavelength-drifting bimodal filter can also achieve pulse shrinkage. In addition, pulse shrinkage together with period doubling can be observed by changing the initial settings.
