Abstract:
The stability and the peak power of a nonlinear-mirror modelocked
Nd:YVO4 laser are significantly increased by the insertion of an
acousto-optic modulator inside the laser cavity. The repetition rate for
reliable operation can be varied in the range 35 kHz – 50 kHz. The laser
generates the most intense and stable mode-locked pulses of width 9 ps
lying underneath a Q-switched envelope of width 110 ns with a Q-switch
modulation frequency of 38 kHz. For 10 W of pump power, a 224 times
enhancement of peak power over that of cw mode-locking is obtained under
reliable Q-switched and mode-locked operation.
