Dr. Maki Kushimoto, Technical Advisor to ULTEC, gave a plenary talk at the 15th International Conference on Nitride Semiconductors (ICNS-15), one of the premier international conferences on nitride semiconductors.
In this plenary talk, we reported the world’s first continuous-wave operation in the UVB wavelength range of 280–300 nm, achieved through a collaborative research effort between ULTEC and Nagoya University. We also discussed the prospects for further expansion of the lasing wavelength range in the future.
Laser diodes operating in the UVB region are expected to enable a wide range of applications, including chemical and biosensing, resin curing, lithography, and materials processing. Continued development toward practical implementation is therefore highly anticipated. ULTEC will continue to advance the commercialization of 280 nm-band laser diodes, while leveraging the wavelength engineering capabilities of semiconductor lasers to expand its product portfolio across a broader wavelength range.
