We report <100 kHz continuous wave diode pumping of Alexandrite lasers in self-Q-switched (SQS) operation using an ultra-compact system. The laser had up to 1:46W of average power with slope efficiency of 49% and M2≤ 1.2. A pulse duration of 657 ns at 138 kHz is obtained, with a corresponding pulse energy and peak power of 9.6 μJ and 14.6 W, respectively. Detailed results related to the laser power, spectrum and temporal profile are provided. A description of the pulse stability with respect to pump power and crystal temperature is also shown. The SQS mechanism is attributed to a time-dependent variation in the refractive index of the population inversion density giving rise to a time-dependent population lens. In a separate study we obtain the value for the variation in polarizability of the excited and ground state that gives rise to the refractive index variation. It is found to be in good agreement with a prior measurement for Alexandrite and in the range measured for other Chromium-doped gain media for which SQS has also been observed.
