Laser Driver

According to the high-tech fabrication of laser diodes, an ultra-stable, low-noise current source is required for their optimized performance. Using a current source instead of a voltage source offers much more tunability, reliability, and control to set the laser output power. According to the wavelength drift and electrical characteristics of the laser diodes, the maximum operating voltage is set to prevent laser damage and failure as a consequence of the current rush and sudden temperature changes.
