Abstract

An all-fiber CVB laser based on a few-mode FBG with switchable radially and azimuthally polarized beam generation has been demonstrated. The CVB fiber laser operates at single wavelength of 1054 nm with a 3 dB line width of less than 0.02 nm, signal-to-background ratio of more than 55 dB. And the output power can reach 75 mW, which is the highest CVB power from all-fiber laser.
