Cool modules extend laser diode lifetimes
New thermoelectrically cooled laser diode modules offer exceptional wavelength and power stability, greatly increased pointing accuracy and significantly extended laser diode lifetime.
Red laser diode provides 10mW in small package
New from Photonic Products is the DL-LS1032, Sanyo's latest red laser diode, which provides 10mW of optical power in the 635nm wavelength band.
The HL8337MG and HL8338MG have typical lasing wavelengths of 830nm and a high optical output power of 50mW CW, a multi-quantum-well structure, a small package size of 5.6mm and a built-in photodiode for monitoring laser output, which allows for easier control of the auto power circuit.
An added benefit of these laser diodes is the low operating current of 75mA, which is the lowest driving current on the market for infra-red 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 optimising both the multi-quantum-well structure and waveguide structure of the laser diodes.
Supplied in a 5.6mm package with 1N (HL8337MG) or 3P (HL8338MG) type common cathode pin configuration, the single longitudinal mode laser diodes have a typical operating current of 75mA, a low typical threshold current of 20mA, low typical operating voltage of 1.9V, monitoring output current of 0.25mA, laser reverse voltage of 2V, PD reverse voltage of 30V at an infra-red wavelength of 830nm.
The operating temperature range is -10 to +60C.
The Opnext HL8337MG and HL8338MG laser diodes are lead (Pb) free in compliance with the RoHS Directive.
All Opnext laser diodes are registered with the FDA of the USA and each laser diode is classified into class II, IIIa, or IIIb, according to the combination of the optical output power and wavelength values. Request a free brochure from Photonic Products ...
