▎ 摘　　要

NOVELTY - Growing graphene involves using novel laser gyro cathode based on surface chemical vapor deposition process, performing cathode surface polishing, cleaning, electrode surface chemical vapor deposition (CVD) to grow graphene. USE - Method for growing graphene. ADVANTAGE - The method enables to grow graphene that solves problem of serious mismatch between the expansion coefficient of the laser gyro cathode and the laser gyro cavity, improves electron emission capability of the cathode, reduces possibility of sputtering on the cathode and prolongs life of the laser gyro.
