  • Gas laser pre-ionization optical monitoring and compensation
    Patent number: 8923356
    Abstract: A slab laser includes first and second slabs defining an ionizing chamber intermediate the first slab and the second slab. A Radio Frequency Power Amplifier (RFPA) generates pulses to the ionizing chamber. The laser has a viewing window with access to the ionizing chamber and an optical sensor mounted to access the ionizing chamber through the viewing window. A controller is in communication with the optical sensor, and varies RFPA pulse power in response to the detection of glowing plasma by the optical sensor.
