The Laser Drivers portfolio is dedicated to operate all types of CW and pulsed semiconductor laser diodes.

The iCs provide fast switching, avoid overshooting by patented circuitries, and feature various monitoring safety functions. Different laser driver control modes are available, such as constant current or constant optical power (requiring a laser diode with monitor diode).

Applications:

• Industrial sensors
• Bar code scanners
• Laser levelling
• Laser printers/copiers
• Laser pointers
