PRESS RELEASE

HL8337MG/HL8338MG

Photonic Products has introduced two high-power, infrared GaAlaS laser diodes from Opnext. The HL8337MG and the HL8338MG are suitable light sources for industrial and medical sensors, distance meters, barcode scanners and high resolution CTP.

The HL8337MG and the HL8338MG have a lasing wavelength of 830nm and a high optical output power of 50mW CW. The diodes are housed in a compact package with a built-in photodiode to monitor laser output for easier control of the auto power circuit.

An added benefit of these laser diodes is the low operating current of 75mA. These laser diodes enable the power consumption to be lowered without sacrificing any optical output power, resulting in greater energy efficiency, extended battery lifetime and significant cost savings for OEMs. This has been achieved by optimising both the multi-quantum well structure and the waveguide structure of the laser diodes.

Featuring a 1N (HL8337MG) or 3P (HL8338MG) type common cathode pin configuration, the single longitudinal mode laser diodes have an operating current of 75mA, a low threshold current of 20mA, low operating voltage of 1.9V, monitoring output current of 0.25mA, laser reverse voltage of 2V, PD reverse voltage of 30V at an infrared wavelength of 830nm. The operating temperature range is –10 to +60°C.

The Opnext HL8337MG and HL8338MG laser diodes are lead free in compliance with the RoHS Directive.

All Opnext laser diodes are registered with the FDA of the United States and each laser diode is classified into class II, IIIa, or IIIb, according to the combination of the optical output power and wavelength values.
