All-fiber staturable absorber Q-switched laser and method for producing staturable absorber Q-switched pulse

摘要

An all-fiber saturable absorber Q-switched laser and the method for producing saturable absorber Q-switched pulses are provided. By locating a saturable absorber fiber in the intensity-enhanced section of a ring resonator, the Q-switched pulses are produced and enhanced. The present application is advantageous in the simple design and effective cost, and is applicable for a variety of fiber-type laser materials.
