Abstract

We fabricate a saturable absorber mirror by coating a graphene- film on an output coupler mirror. This is then used to obtain Q-switched mode-locking from a diode-pumped linear cavity channel waveguide laser inscribed in Ytterbium-doped Bismuthate Glass. The laser produces 1.06 ps pulses at ~1039 nm, with a 1.5 GHz repetition rate, 48% slope efficiency and 202 mW average output power. This performance is due to the combination of the graphene saturable absorber and the high quality optical waveguides in the laser glass.

摘要

我们通过在输出耦合镜上涂覆石墨烯薄膜来制造可饱和吸收镜。然后将其用于从掺镱铋酸盐玻璃中写入的二极管泵浦线性腔通道波导激光器中获得调Q锁模。该激光器在~1039nm波长处产生1.06ps的脉冲，重复频率为1.5GHz，斜率效率为48%，平均输出功率为202mW。这种性能归因于石墨烯可饱和吸收体与激光玻璃中高质量光波导的结合。
