P. Glas et al., HIGH-REPETITION-RATE FIBER LASER COUPLED TO A LINEAR CAVITY GENERATING PICOSECOND PULSES, Fiber and integrated optics, 17(3), 1998, pp. 207-212
An experimental investigation is presented for obtaining picosecond (p
s) pulses at a repetition rate of 11 GHz ruing a fiber laser coupled t
o an external cavity. Without applying active mode locking and without
a nonlinear element in the coupled cavity, pulses of about 15 ps with
an average power of 20 mW have been generated using a (cw) diode pump
laser. The pulse duration decreases with increasing repetition rate.
