Ultraviolet laser diode delivers 1.0 W output at 379 nm

January 19, 2026 By Puja Mitra Leave a Comment

Nuvoton Technology has started mass production of the KLC330FL01WW, a 379 nm ultraviolet semiconductor laser delivering 1.0 W optical output in a TO-9 CAN package. The device combines a short UV wavelength with improved heat dissipation and extended operating lifetime, addressing the requirements of maskless lithography and other precision optical systems used in advanced semiconductor packaging. It also expands Nuvoton’s lineup of mercury lamp replacement solutions for applications including resin curing, marking, 3D printing and biomedical equipment.
