A Compact Universal Power Supply for Laser Diodes.
Abstract
A compact universal power supply for laser diodes was designed and built. The power source will supply current for laser diodes with forward operating current up to approximately 350 milliamps (mA). The power supply has a feedback stage, a slow start circuit, ac transient suppression, and digital optical power meter. The power supply is based upon a Toshiba design, with modifications in the feedback loop to provide utility for a wide range of laser diodes. The power supply was built into a compact unit and tested on: a Toshiba TOLD9200 visible laser diode with optical power of 3 milliwatts (mW) at an operating current of approximately 75 mA; an OKi OL308A-75 high power infrared laser diode with optical power of 80mW at an operating current of approximately 220 mA; and a Sharp near infrared laser diode with optical power of 3 mW at an operating current of approximately 57 mA.
