With its new A4 series, Arima Lasers has significantly improved the automatic power control (APC) of its compact APC laser diodes. Whenever an eye-safe radiation beam is required, this new model offers additional protection: If an internally set operating current level is exceeded, the laser diode shuts down automatically.
The latest laser diodes are insensitive to electrostatic discharges of up to 10 kV and guarantee a stable output power at supply voltages of 2.5 to 6.0 VDC. As in its predecessor, the control is located as an ASIC on the same chip as the photodiode and the emitting laser diode, and it is integrated in compact TO housings (3.3 mm or 5.6 mm). These laser diodes are available in different wavelengths between 635 nm and 850 nm.
APC laser diodes are used, for example, in high-precision measuring devices.
