Switchable single-double frequency multi-wavelength Brillouin Raman fiber laser based on micro-air cavity misalignment

This study experimentally demonstrates a switchable single-double frequency spacing multi-wavelength Bril�louin Raman fiber laser (MW-BRFL). The switching functionality was assisted by a micro air cavity (MAC) that was constructed by lateral misalignment of two cleaved fiber facets. Experimental r...
