Abstract

Flashlamp is an optical pumping source for Nd:YAG laser. The aim of this project is to design and construct a driver for xenon flashlamp. The design composed of four main circuits that are: simmer supply, discharge capacitor, control unit and ignition circuit. Initially, the driver was feed in with a pulse of 1.5 ìs and 3.68 V to open the gate of SCR. The pulse then induced a giant pulse of 4.34 kV and 5 ìs to ignite and cause pre-breakdown in the flashlamp. A voltage between electrodes was formed drop to 120 V and maintain current of 120 mA. Discharge capacitor circuit was triggered flashlamp with 600 V and the peak current of 149 A. Brilliance white lights have been flashed and produced broad band spectra with majority at 823 nm.
