Nonlinear polarization rotary mode-locked Raman fiber laser

by Laser Explorer Posted on 792 views
Nonlinear polarization rotation is the most common equivalent saturable absorber in fiber lasers. This technique exploits the nonlinear refractive index and birefringence effects in the fiber, allowing different parts of the pulse to accumulate differently in the laser cavity. The phase shifts, thus evolving into different polarization states, and then polarization selection by the analyzer, ...
