Integrated laser/FLIR rangefinder

A laser transmitter is comprised of a power converter connected to a power conditioner for converting the preregulated dc power to high voltage dc required for laser discharge. A pulse forming network is connected to the power converter, for generating short, high voltage high current pulses. A laser cavity is connected to the PFN for generating laser pulse beams in response to the PFN output. The laser cavity includes a housing with two thermal-expansion-matched metal electrodes sandwiched between opposing preionization electrodes mounted in wells formed in the ceramic housing. The ends of the wells are ceramic to form dielectric between the cavity electrodes and the preionization electrodes for capacitively coupling the preionization electrodes for cavity chamber and producing coronas in the laser cavity which produce UV radiation in the cavity without arcing. The laser cavity has glass-frit-sealed metal end-caps, a solder sealed out-coupler assembly, a total reflector mirror and total reflector mirror adjustment mechanism.
