摘要
利用高分子聚合物聚乙烯醇（PVA）易成膜且机械性能优良的特点，将微米尺寸的石墨烯薄片制成大尺寸的石墨烯-PVA薄膜。分别测量了石墨烯-PVA薄膜与石墨烯片的拉曼光谱，发现二者具有同样的特征。研制了用该石墨烯-PVA薄膜作为饱和吸收体，具有环形腔结构的被动锁模掺铒光纤激光器，获得了峰值波长1532.75 nm，重复频率8.7 MHz，脉冲宽度10.29 ps的脉冲序列。
Abstract
A graphene-PVA film is fabricated by using polyvinyl alcohol(PVA), which provides excellent mechanical property and easy operation. Raman spectra of the graphene-PVA film and graphene sheets are measured, which show that the spectra have the same characteristics. The passively mode-lock Er-doped fiber laser with graphene-PVA film as saturable absorber is made, which produces the mode-locked pulses with duration of 10.29 ps, peak wavelength of 1532.75 nm, and repetition rate of 8.7 MHz.
