▎ 摘　　要

NOVELTY - The device has a graphene thin film (1) attached to an optical fiber head (2). A graphite chuck is provided for reusable usage of saturated absorbent combined with amplitude or phase modulation mold for realizing mixed mode-locked process for laser. USE - Graphene based device for performing mode-locked process for solid laser or space laser (all claimed). ADVANTAGE - The device is provided with low absorption intensity, and ensures fast recovery time and adjustable modulation depth. The device is low in cost. DESCRIPTION OF DRAWING(S) - The drawing shows a block diagram of a device for performing mode-locked process based on graphene. Graphene thin film (1) Optical fiber head (2)
