Me. Fermann et al., PASSIVE-MODE LOCKING BY USING NONLINEAR POLARIZATION EVOLUTION IN A POLARIZATION-MAINTAINING ERBIUM-DOPED FIBER, Optics letters, 18(11), 1993, pp. 894-896
By using a new simple cavity design, in which both linear and nonlinea
r polarization evolution are reproducibly controlled, we demonstrate p
assive mode locking in a Fabry-Perot-type erbium fiber laser. The lase
r generates stable trains of pulses as short as 200 fs with an energy
content of 70 pJ at repetition rates as high as 100 MHz.
