Abstract

A drive system can be provided for a radio frequency excited gas laser. The gas laser can be a CO2 laser. The drive system can comprise a microprocessor and/or microcontroller operable to generate an amplifier drive signal and to gate the amplifier drive signal in accordance with a received command input. A RF power amplifier can be provided operable to receive the amplifier drive signal and to provide a laser drive signal proportional to the amplifier drive signal. The microprocessor and/or microcontroller can provide a network interface for receiving control inputs from and/or providing information regarding operation status to a remote terminal.
