Abstract :
Summary form only given. This paper presents the first experimental results towards mode-locking of a Cr/sup 4+/:YAG microchip laser. Kerr-lens mode-locked operation of an 8.2 mm long Cr/sup 4+/:YAG microchip laser using a Q-switched Nd:YVO/sub 4/ laser for pumping is demonstrated. Q-switched mode-locked operation at a fundamental repetition rate of 10 GHz with 200 fs pulses and output powers up to 300 mW is, observed. Also passive Q-switched mode-locking with saturable Bragg-reflectors is demonstrated. Numerical simulations of the temporal pulse-shaping dynamics in the micro-chip laser are presented. These simulations are used to determine the minimum intracavity energy needed to overcome Q-switching in order to obtain a continuous-wave mode-locked pulse train.
