Stable pulsed laser diode driver for rangefinder

This article presents comparison of methods of driving pulse laser diodes. Based on theresults of shown analyses, the new design of pulse laser diode driver, using MOSFET transistor, wasdeveloped. The driver allows stable pulse laser pumping that is required for stable pulse laser emissionin high accuracy lasers’ rangefinders. Design and theory of operation of the driver is shown, as wellas working parameters acquired by testing of the prototype module.[b]Keywords[/b]: pulse laser driver, pulse laser rangefinders, semiconductor pulse laser driver
