Abstract

This work introduces diode lasers to the non-expert and demonstrates the feasibility of constructing a homemade diode laser controller as a cheaper alternative to commercially available components for use in undergraduate laboratories. We designed and implemented a diode laser controller composed of readily available electronic parts. Using only a voltmeter, an ammeter, and the custom-built controller, we are able to measure laser diode performance by obtaining accurate L-I curves.
