Ushio smashes 640nm laser diode output power record with HL63653TG

Ushio Inc. has launched a record-breaking red laser diode, HL63653TG, for compact projectors, levellers and laser modules. The new 200mW laser diode delivers the world’s highest output power for the 640nm wavelength class from a tiny 3.8mm package.

The demand for small projectors, such as pico projectors and other types of portable projectors, is growing thanks to the increasing demand for small, mobile electronic devices. Both LEDs and laser diodes are suitable options as the light source in these tiny projectors. However, laser-based pico projectors have advantages over LED-driven devices such as higher luminance and a wider colour gamut. Also, due to the lack of light dispersion, laser projectors are focus-free.

Currently, Ushio’s laser diodes offer the highest output power, smallest packages and performance features,such as high reliability and high power conversion efficiency *1. Furthermore, Ushio’s laser diode engineers have been able to concentrate on creating a product that facilitates further downsizing, weight reduction and lowering the power consumption of small, often battery-powered, projectors. With this background, Ushio developed and commercialised the HL63653TG, which achieves 200mW optical output at a wavelength of 640nm, while maintaining the tiny 3.8 mm package.
