Abstract

A hundred-watt level spatial mode switchable all-fiber laser is demonstrated based on a master oscillator power amplifier scheme. The mode switchable seed laser is implemented by integrating a homemade acoustically induced fiber grating (AIFG) mode converter inside the cavity, and the output power was scaled to > 100 W in both LP01 and LP11 mode. Fast mode switching with millisecond scale switching time between LP01 and LP11 mode while operating in full power is realized through the AIFG driven by radio frequency modulation. This work could provide a good reference for realizing high-power agile mode-switchable fiber lasers for practical applications.
