Opnext has released its HL6387TG laser diode for use in miniature display applications.
The new diode can be built into miniature display systems including those in personal computers, mobile phones and other mobile devices.
This 3.8mm small packaged laser diode with single longitudinal mode allows for 60mW continuous operation in a 640nm wavelength band. The HL6387TG incorporates a smaller φ3.8mm package while still retaining the high reliability of the product. The output power of the laser diode also remains constant despite the decrease in the ratio of the stem area by 50 per cent. The wavelength band of the red area is 642nm which is optimal for red light display. The single longitudinal mode also enables higher resolution of displayed images by focusing laser light into a small spot.
