▎ 摘　　要

NOVELTY - The laser has a bottom plate whose upper surface is fixedly equipped with a front shell, where a rear side of the front shell is provided with a rear shell. A right side of the front shell is connected with a placing mechanism. An excitation source assembly generates excitation and transfers high-energy beam generated by atomic excitation to a total mirror assembly. The total reflection mirror assembly totally reflects high-energy beam generated by the excitation source to increase the light intensity of the high-energy beam. The total mirror assembly is connected to a Q-switch assembly through an optical path. USE - Carbon nanotube and graphene saturable absorber-based optical fiber laser. ADVANTAGE - The output fiber is set as a saturable absorber so as to improve quality and purity of the laser. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a carbon nanotube and graphene saturable absorber-based optical fiber laser.
