Dual-Wavelength of Single Polarized Fiber Laser Based on Common Active Fiber

利用游标卡尺原理实现的单偏振掺铒光纤激光器

“…However, two orthogonal linear polarization modes will exit simultaneously in these lasers if no special measures have been taken. Consequently the polarization mode competition will be introduced and induce the power perturbation due to little difference between the mode-propagation constants of the two polarization modes [1,2] . So a single-polarization fiber laser is needed to improve the power stability of the output lasing line.…”
