采用化学气相沉积技术制备了大面积、高质量的三明治结构单层石墨烯可饱和吸收体。利用石墨烯可饱和吸收体实现了激光二极管泵浦Yb，Y：CaF2激光器的锁模运转。在没有额外负色散元件的情况下，在1051 nm处产生了4.8 ps的脉冲。脉冲重复频率为60 MHz。
The large-area and high-quality monolayer graphene saturable absorber with a sandwich structure is prepared by the chemical vapor deposition technique. Using graphene saturable absorber, the mode locking operation of a diode-pumped Yb,Y:CaF2laser is demonstrated. Without extra negative dispersion elements, 4.8 ps pulses are yielded at 1051 nm. The pulse repetition rate is 60 MHz.
