Oclaro launches 700mW 638nm red laser diode in 5.6mm package for laser TV and projection

In booth #940 (South Hall, Moscone Center) at the Photonics West 2014 show in San Francisco, CA (4-6 February), optical component, module and subsystem maker Oclaro of San Jose, CA, USA is launching the HL63193MG, a 638nm-wavelength red laser diode with 700mW output power, multiple transverse mode and a small 5.6mm-diameter TO package, targeted at the emerging laser TV and projection markets.

High-power red laser diodes are a critical building block for laser TV and display applications, says Oclaro. New projectors require several 10s of Watts of combined red, green and blue laser optical power to meet expectations for brightness and image quality. Oclaro says its 700mW red laser diodes enable users to maximize overall output power without increasing the number of components inside the projector.

With a high wall-plug efficiency of about 38%, the HL63193MG reduces the electrical power consumption and also the amount of heat that has to be removed from the package, allowing more compact and integrated designs, the firm claims. The new aluminum gallium indium phosphide (AlGaInP) red laser diode’s features also include: an operating temperature up to 40°C and an operating current of 900mA.

“We are ready for mass production with this product [after completing qualification in December] and believe it will enable new and exciting consumer applications for red lasers,” says Yves LeMaitre, president of Oclaro’s Optical Connectivity Business.
