ABSTRACT:
A circuit for providing current to a laser tube permits high current, high output voltage, and high frequency modulation response (e.g., up to about 1 MHz, in one embodiment) with low power dissipation. This is accomplished by combining the output current from two current sources, one of which is a high amplitude low frequency current mode switched mode power supply, while the other current source is a low amplitude, high frequency current source.
