Abstract
Integrated laser head apparatus is disclosed for producing high energy pulses in pulsed gas lasers. The present invention provides high energy pulses over short time durations suitable for laser rangefinder systems due to an improvement in the arrangement of energy storage capacitors (22, 24) which keeps circuit inductance to a minimum. The pair of nested, ceramic capacitors (22, 24) are substantially cylindrical and are coupled through thin conductive layers (23). The capacitors are charged by a spark gap trigger (14), an inductor (18), and a charging resistor (52). The capacitors (22, 24) enclose a pressure vessel (28) which further encloses a laser resonator (12) including a laser output coupler mirror (42), totally reflective mirror (44), discharge electrodes (32, 34) and a central chamber (30) which contains a pressurized gaseous phase laser medium. The high voltage discharge electrode (32) is disposed coaxially with the surrounding capacitors (22, 24).
