We report on mode-locking of a Cr:YAG laser at 1516 nm using a monolayer graphene-based saturable absorber of transmission type generating 91 fs pulses with a Fourier product of 0.38 at an average output power exceeding 100 mW. Stable single-pulse mode-locked operation without any sign of Q-switching instabilities or multiple pulses is achieved.
我们报告了使用基于单层石墨烯的透射型可饱和吸收体在 1516nm 处对 Cr:YAG 激光进行锁模，产生了 91fs 的脉冲，其傅里叶乘积为 0.38，平均输出功率超过 100mW。实现了稳定的单脉冲锁模运行，没有任何 Q 开关不稳定性或多脉冲的迹象。
