摘要
RF power can be delivered to excite the discharges of laser systems using a series of fast semiconductor switches arranged in an “H”-bridge configuration. Such a configuration can amplify the output of crystal controlled RF oscillators, using a low voltage power supply, thereby reducing the number of necessary amplification stages while obtaining the desired output at the necessary frequencies. A power amplifier operating in a high efficiency mode can serve as a switch, thereby converting a rounded signal produced by an RF transformer connected between arms of the H-bridge into a square-wave-like signal, while providing the necessary output power.
