ABSTRACT:
An efficient power supply employs a high current switching transistor to pulse a flashlamp for optical pumping in lasers, such as an Nd:YAG laser at high pulse repetition frequencies. The pulsing circuit offers a simple, flexible, and precise means of pump pulse control. Flashlamp simmer current is provided from the constant dc voltage source with a resistor in parallel with the switching transistor.
