Output characteristics of acousto-optical cavity dumped Tm:YAG ceramic laser

We have demonstrated an acousto-optical cavity dumping Tm:YAG ceramic laser at a wavelength of 2012.6 nm. The pulses were coupled out of the cavity by the lateral surface when radio frequency was added into the acousto-optical modulator. The minimum pulse width of the cavity dumped Tm:YAG ceramic laser is 31 ns, corresponded with an output power of 180 mW and a repetition rate of 200 kHz. In addition, the unsmooth pulse shape of the cavity dumped Tm:YAG ceramic laser was numerically calculated.
