Opnext 830-nm Laser Diodes
Dec 2007
Photonic Products Ltd.Request Info
HATFIELD BROAD OAK, England, Dec. 10, 2007 -- Photonic Products Ltd., an authorized distributor, said it now has available two new high-power, infrared wavelength GaAlAs (gallium aluminum arsenide) laser diodes -- the HL8337MG and the HL8338MG -- manufactured by Opnext Inc. (formerly Hitachi).

The two new laser diodes are ideal as light sources for industrial and medical sensor applications and as a light source for various other types of optical equipment, such as distance meters, barcode scanners and high-resolution CTP, said Photonic Products, a StockerYale company.

Opnext830.jpgThe HL8337MG and the HL8338MG have a lasing wavelength of 830 nm typ. and a high optical output power of 50 mW CW, a multiquantum well structure, a small package size of 5.6 mm and a built-in photodiode for monitoring laser output which allows for easier control of the auto power circuit.

An added benefit of these diodes, Photonic Products said, is the low operating current of 75 mA, which is the lowest driving current on the market for infrared applications. 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 optimizing both the multiquantum well structure and waveguide structure of the diodes.

Supplied in a 5.6-mm package with 1N (HL8337MG) or 3P (HL8338MG) type common cathode-pin configuration, the single longitudinal mode laser diodes have an operating current of 75 mA typ., a low threshold current of 20 mA typ., low operating voltage of 1.9 V typ., monitoring output current of 0.25 mA, laser reverse voltage of 2 V, PD reverse voltage of 30 V at an infrared wavelength of 830 nm. The operating temperature range is -10 °C 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 in the US and each diode is classified into class II, IIIa, or IIIb, according to the combination of the optical output power and wavelength values.
