▎ 摘　　要

NOVELTY - The light pulse generator has an amplifying circuit (19) whose output end is connected with input end of a piezoelectric ceramic driver (20). The PZT piezoelectric ceramic portion (21) is connected with output end of piezoelectric ceramic driver and optical coupler (8). A dispersion compensating optical fiber (23) is connected with a graphene saturable absorber (24). A single mode optical fiber (25) is connected with the graphene saturable absorber and erbium-doped optical fiber (26). The erbium-doped optical fiber is connected to PZT piezoelectric ceramic portion. USE - High-stability light pulse generator. ADVANTAGE - The generation of the stable ultra-short light pulse is enhanced. The operation of the light pulse generator is simple and accurate control is achieved. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the high-stability light pulse generator.
