QD LASER

QD Laser, Inc. is a Japanese high-tech company specializing in the research, development, and commercialization of quantum dot semiconductor laser technology. Founded in 2006 as a spin-off venture from Fujitsu Laboratories Ltd. and the University of Tokyo, the company is headquartered in Kawasaki, Japan and is listed on the Tokyo Stock Exchange (TSE Growth: 6613).

Core Technology & Products

QD Laser's core technology is its proprietary quantum dot laser, which uses "quantum dots" in the light-generating active layer. This provides superior energy efficiency, heat resistance, and temperature stability compared to conventional quantum well semiconductor lasers. The company operates through two main business segments:

Laser Device Business: Manufactures and sells high-performance semiconductor lasers and epitaxial wafers for communications, industry, and sensing. Key products include 1240-1310 nm quantum dot lasers, DFB lasers for material processing, and compact visible lasers.
Laser Eyewear Business: Develops and sells RETISSA series retinal scanning laser eyewear, which projects images directly onto the user's retina to assist those with visual impairments.

Markets & Applications

QD Laser serves a broad range of fields, including telecommunications, manufacturing, medicine, and consumer products. Its solutions are used in silicon photonics, precision machining, sensing, and biophotonics. The company is recognized as a pioneer in the commercialization of quantum dot laser technology.
