Safe APC Laser Diodes - Diodes with Built-In Shut-Off Circuity for Eye-Safe Applications

18 Dec 2017

The new “A4” series of compact APC laser diodes offers additional protective

functionality for applications in which an eye-safe source of radiation is required. The

“automatic power control” (APC) will shut down the laser once a specific operating

current is exceeded.

The A4 laser diodes are insensitive to electrostatic discharges of up to 10kV and a

stable output power is guaranteed for supply voltages of 2.5 to 6VDC. As was the

case for the devices predecessor, the APC is located at an ASIC on the same chip

as the photodiode and the emitting laser diode, and is integrated in compact TO

housings (3.3mm or 5.6mm). Diodes from this series are available at wavelengths

between 635nm and 850nm and lend themselves well to applications in highprecision

measurement.
