  • Laser excitation system
    Patent number: 4709373
    Abstract: A laser excitation system is disclosed in which the laser medium is preionized by a UV-generating spark array and is excited by an electric avalanche discharge. The preionized state is sustained during the discharge by a second spark array and an isolated discharge capacitance. In this manner, a continuous ionization state during discharge is achieved.
