摘要

摘要:将纳米氧化钪(Sc2O3)粉末包埋在聚乙烯醇薄膜中，利用Sc2O3薄膜的可饱和吸收特性产生调q和锁模脉冲。调q激光器工作在1560.5 nm的中心波长，最大脉冲能量为65.6 nJ，斜率效率为4.4%。通过在环形腔中增加200 m的单模光纤，实现了自启动锁模EDFL。锁模脉冲的中心波长为1565.4 nm，重复频率为1.0 MHz，脉冲持续时间为3.50 ps。

Sc2O3 PVA Film for Switching and Mode-Locking Application in Erbium-Doped Fiber Laser Cavity

ABSTRACT We generated Q-switched and mode-locked pulses by making use of the saturable absorption characteristic of scandium oxide (Sc2O3) film, which was obtained by embedding Sc2O3 nanopowders into polyvinyl alcohol film. The Q-switched laser operated at center wavelength of 1560.5 nm with the maximum pulse energy of 65.6 nJ and 4.4% slope efficiency. With the addition of a 200 m extra single-mode fiber in the ring cavity, a self-starting mode-locked EDFL was implemented. The mode-locked pulses operated at a central wavelength of 1565.4 nm with a repetition rate of 1.0 MHz and a pulse duration of 3.50 ps.

期刊介绍： Fiber and Integrated Optics , now incorporating the International Journal of Optoelectronics, is an international bimonthly journal that disseminates significant developments and in-depth surveys in the fields of fiber and integrated optics. The journal is unique in bridging the major disciplines relevant to optical fibers and electro-optical devices. This results in a balanced presentation of basic research, systems applications, and economics. For more than a decade, Fiber and Integrated Optics has been a valuable forum for scientists, engineers, manufacturers, and the business community to exchange and discuss techno-economic advances in the field.
