Abstract
Abstract In a laser transmitter employing a glass laser rod, the laser rod, a flashlamp for exciting the rod, and pump light reflector are encapsulated in a resilient potting material and the resulting assembly is secured in a frame by means of a resilient potting material. The reflectors defining the laser cavity together with other elements of the cavity are also mounted in pockets defined in the frame. A circuit is provided to generate high voltages from a low voltage supply for energizing the flashlamp and for Q switching the laser cavity by means of a Pockels cell.
