Polarization independent picosecond fiber laser. |
摘要 |
<p>In a polarization insensitive fiber laser, the optical path comprises an amplifier (58) and a pair of 45 degree Faraday rotators (56,60) positioned on either end of the fiber gain source, whereby the resulting laser is insensitive to external perturbations with respect to known entrance and exit polarization states of the laser light and modelocking, both passive and active, is possible. The amplifier (58) comprises an Erbium-doped fiber which is coupled to a wavelength division multiplexer (62) and a single mode fiber (74). <IMAGE></p> |
