摘要
采用垂直蒸发法分别在玻璃和石英衬底上淀积单壁碳纳米管和氧化石墨烯材料来制作碳基可饱和吸收体。利用单壁碳纳米管作为饱和吸收体,实现了NdYVO4激光器被动锁模,最高输出功率为3.6 W,斜率效率为31%,脉冲宽度为7.6 ps,重复频率为75 MHz。利用氧化石墨烯作为可饱和吸收体,实现了NdGdVO4激光器被动锁模,最大输出功率为1.1 W,斜率效率为11.3%,脉冲宽度为4.5 ps,重复频率为70 MHz。
Abstract
Single walled carbon nanotubes and graphene oxide are deposited on glass and quartz by vertical evaporation method, respectively. By using single walled carbon nanotubes absorber, passively mode locked NdYVO4 laser is obtained. The maximum output power is 3.6 W, the slope efficiency is 31%, the pulse duration is 7.6 ps and the repetition rate is 75 MHz. By using graphene oxide absorber, passively mode locked NdGdVO4 laser is achieved. The maximum output power is 1.1 W, the slope efficiency is 11.3%, the pulse duration is 4.5 ps and the repetition rate is 70 MHz.
