Linearly Polarized Polarization-Maintaining Er3+-Doped Fluoride Fiber Laser in the Mid-Infrared
文献摘要：
We demonstrated the ～2.8-μm and ～3.5-μm linearly polarized continuous wave (CW) laser outputs from a polarization-maintaining (PM) Er3+-doped fluoride fiber laser. By introducing a film polarizer into the cavity to select the laser polarization orientation, the ～2.8-μm linearly polarized CW laser with a high polarization extinction ratio (PER) of ～23 dB and maximum output power of 2.37 W was achieved under double-end pumping at 976 nm. By adding another 1981-nm pump source simultaneously, the ～3.5-μm linearly polarized CW laser was also obtained, giving higher PER of ～27 dB and maximum output power of 307 mW which is only limited by the available power of 1981-nm pump. To the best of our knowledge, this is the first report on a mid-infrared linearly polarized CW PM fiber laser in the >2.5-μm mid-infrared region. This work not only opens up opportunities for some new mid-infrared applications, but also provides a promising platform for developing high-stability and versatile mid-infrared laser sources.
