QD Laser is headquartered in Kawasaki, Kanagawa. We develop, manufacture and sell state-of-the-art lasers including quantum dot lasers.
Qdlaser were the first in the world to successfully develop and mass produce quantum dot lasers for communications that operate without current adjustments. Our continuous string of innovative products includes picosecond short-pulse DFB lasers for precision processing; current injection-type green, yellow-green and orange lasers for the biological sciences; quantum dot laser arrays for silicon optical circuits; broadband gain chips for ophthalmic testing equipment; and retinal imaging laser eyewear.
QD Laser supplies high-performance semiconductor lasers and wafers on GaAs substrate as a platform for communications and industrial applications. It engages in joint R&D to create new value with Arakawa & Iwamoto Laboratory (University of Tokyo) and Fujitsu Laboratory.
