Opnext launches first 640nm/60mW red laser, targeting miniature displays

Optical module and component maker Opnext Inc of Eatontown, NJ, USA has launched what it claims is the first 640nm/60mW red laser diode, accelerating the firm’s entry into the miniature display market. The new HL6387TG can be built into miniature display systems, including those in personal computers, mobile phones and other mobile devices.

Tadayuki Kanno, Opnext's senior VP, Device Business Unit, claims that the new laser can provide better color reproducibility on a cell phone or other portable device, helping to meet consumer demand for new applications in the miniature display market.

The single-longitudinal-mode laser allows continuous operation at a power output of 60mW in the 640nm wavelength band. high reliability remains high despite the HL6387TG’s small (3.8mm) package. Output power also remains constant despite a decrease in the ratio of the stem area by 50%. 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 the displayed images by focusing the laser light into a small spot, says the firm.
