Oclaro's high power HL63193MG laser diode, available from the Optoelectronics Company, is now in mass production. The diode is ideal for the laser TV, video projection and show laser markets.
The AlGaInP HL63193MG is a multi-transverse mode laser diode with TM mode oscillation in a 5.6mm diameter TO package. It offers a 700mW optical output power at a typical centre lasing wavelength of 638nm, has an operating temperature up to 40°C, typical operating voltage of 2.2V, LD reverse voltage of 2V, with a typical threshold current of 200mA and operating current of 820mA. The typical beam divergence parallel to the junction is 9 degrees, perpendicular to the junction is 35 degrees.
The HL63193MG offers a high wall-plug efficiency rate of 38 per cent which reduces both its electrical power consumption and the amount of heat that has to be removed from the package, allowing for a more compact and integrated design. High wall-plug efficiency, particularly for high-power lasers, is critical as it not only cuts down the electricity bill but also reduces the demands on electrical installations and on the cooling system, resulting in a reduction of the size of the laser system. All Oclaro diodes are RoHS compliant.
