Abstract
Raman dissipative soliton is generated in a mode locked polarization maintaining fiber laser with a nonlinear optical loop mirror. Ultrafast Raman laser with a repetition rate of 1.23 MHz is obtained. Signal to noise ratio of the radio frequency spectrum of the Raman dissipative soliton is as high as 85 dB. As the pump power increasing, the pulse energy and the spectral width increase, while the pulse width decreases. The highest pulse energy and lowest pulse width is 1.23 nJ and 63 ps, respectively. It is the first report of Raman dissipative soliton generation from an all polarization maintaining mode locked fiber laser to the best of our knowledge. This configuration provides a method to obtain linearly-polarized ultrafast laser at flexible wavelengths.
