Miniaturized Q-switched diode pumped solid state laser
A compact Q-switched solid state laser for producing short high peak power pulses is described comprising: a miniaturized solid state laser rod; cavity forming means for defining a compact resonant cavity which contains the laser rod, the cavity forming means including output coupling means for extracting laser pulses from the cavity; laser diode pumping means positioned to longitudinally end pump the laser rod and to match the pumping volume to the mode volume in the laser rod; a miniaturized Q-switch mounted in the resonant cavity in a position to introduce a loss in the cavity so the rod can be pumped to store energy without lasing, and to remove the loss so that lasing in the cavity occurs with stored energy being dumped into a short high peak power pulse.
