NOVELTY - The utility model claims a mode-locked pulse laser based on GO-MoS2 saturable absorber, comprising orderly connected semiconductor laser, coupling lens group, Er: KGW crystal, a first plano-concave mirror, a second plano-concave mirror, a reflector, a GO-MoS2 saturable absorber and an output mirror; the concave surface of the first plano-concave mirror is opposite to the concave surface of the second plano-concave mirror; the reflecting surface of the reflector faces the concave surface of the second plano-concave mirror and the input end of the GO-MoS2 saturable absorber; the output end of the GO-MoS2 saturable absorber faces to the output mirror; the GO-MoS2 saturable absorber and the output mirror are arranged in parallel. The utility model makes the light intensity of the continuous light be the minimum loss while obtaining the maximum laser pulse, outputting strong pulse laser.
