摘要：

We present a Tm-doped fiber laser operating around 1.9 mu m by bi-directional pumping with 1.6 mu m-band laser diodes. The laser output pulse is built by using a gain-switching pump pulse with a bias pump pulse. The output pulse power is measured to 119 mW when the bias pump power and the gain-switching pulse power are 71.7 and 46.6 mW, respectively. The output power is changed by tuning the feedback ratio of the variable-ratio output coupler and maximized at the feedback ratio of 0.81. The laser wavelength varies from 1.88 to 1.92 mu m depending on the length of the Tm-doped fiber. (C) 2011 by Astro Ltd. Published exclusively by WILEY-VCH Verlag GmbH & Co. KGaA
