High speed switching power supply for a light controlled laser system |
摘要 |
A high speed switching power supply for a laser system is disclosed. In the preferred embodiment, proportional-plus-derivative feedback of the emitted light controls the duty cycle of the MOS-FET switching transistor to vary the d.c. voltage level applied across a storage capacitor from a d.c. power supply. The storage capacitor is connected across a laser tube to apply its stored voltage thereto. The MOS-FET transistor permits high speed switching. The derivative portion of the feedback damps out oscillatory tendencies in the feedback loop to permit increased loop bandwidth. The combination of the MOS-FET transistor and proportional-plus-derivative feedback permits the laser output to be controlled in a voltage-controlled mode.
