Frequency-modulation mode locking of a Nd(3+)-doped fiber laser.
Frequency-modulation mode locking of a Nd(3+)-doped fiber laser operating at 1.09 microm using a bulk phase modulator is reported. The resulting pulses have a 20-psec duration (FWHM) and a peak power of 1 W. A least-squares fit to the second-harmonic-intensity autocorrelation trace and the time-bandwidth product of 0.30 +/- 0.04 suggest that the pulses are bandwidth limited with a sech(2)-type profile.
