In this paper, we present a high-speed laser diode driver that has a very sensitive analog modulation input. It is designed to be part of the electronics of a laser projection system and it is responsible for the rendering of a color channel with accurate beam intensity during laser animations. The fast response time and the very good sensitivity result in excellent projection quality. Depending on the laser diodes, the laser driver can be adjusted to waste very little power in the form of heat, which enables its application in confined spaces and without an attached heatsink. Its compact size and the careful positioning of the electronic components facilitate the installation into the laser projector enclosure.
