Pico-Projectors

Pico projector is an emerging technology that applies an image projector in a handheld device. There is an increasing demand to make the projector more convenient and comfortable, where the laser projection is a solution to provide bright images at low power consumption and focus-free operation, i.e., the image is always in focus. A key to laser projectors is high-performance green lasers. The combination of a 1064nm Distributed Feedback (DFB) laser and SHG device is to provide superior performance to GaN-based direct green lasers in its pure green color of 532nm, higher power up to 80mW or more, better wall plug efficiency, and higher operation temperature. Please note that the yellow laser of 559nm is possible using 1118nm DFB laser to improve colour reproduction.
