Laser diode controllers contain many elements needed to power, control and protect a complete laser system. AMS Technologies provides a range of products in PC board and bench top packaging formats that perform the functions of driving the laser diodes (current source) as well as providing the temperature controller in order to maintain the stability of the laser diodes. The diode controllers provide an output current starting at 0.8 A at 3 V up to 120 A at 24 V for high power applications and feature temperature stabilisation to 0.1°C.
