Ushio launches HL63623HD high-power red laser diode for projectors
NEWS RELEASE: March 2021
Due to their long lifetime, in comparison with conventional lamps, laser projectors are increasing in popularity. The total cost of ownership is reduced through the elimination of xenon lamp replacement, while the use of red laser diodes achieves excellent colour reproduction with high efficiency. Ushio Inc. has created the high-power red laser diode, HL63623HD, primarily for use as a light source for laser projectors.
Over recent years Ushio has contributed to the expansion of laser projectors through their proactive suggestion of high-power red LD products within the market. In 2017, they launched two types of emitters: the single emitter HL63283HD (637 nm, CW 1.2 W) and the dual emitter HL63290HD (638 nm, CW 2.2 W, pulsed 2.8 W). In 2019, they launched HL63520HD, a dual emitter with an impressive pulsed optical output power of 3.5 W (638 nm, CW 2.4 W, pulsed 3.5 W). As such, Ushio has contributed to the optimisation of the optical design of various projectors by offering a varied line-up of products with differing light output and emitting options.
The new HL63623HD is a single emitter LD with CW optical output power of 1.5 W. They have optimised the crystal growth conditions and chip structure in order to maintain high optical output power and high efficiency, even in high temperature environments. They successfully improved the chip performance by significantly refining the light extraction efficiency and heat dissipation from the chip.
As a single emitter LD, HL63623HD has achieved an outstanding CW optical output power of 1.5 W and a lifetime of 20,000 hours, contributing to the higher brightness, lower cost, and longer life of laser projector light sources. A CW optical output power of 1.0 W at 55°C has also been achieved, allowing for further simplification of the cooling system. Although HL63623HD is well-suited to laser projectors, it is also compatible with display and illumination applications in the 638nm region that require high power red LDs with high visual sensitivity.
