On January 29, at the Photonics West 2024 conference held in San Francisco, DoGain released the latest progress in 915nm high-power and high-efficiency semiconductor lasers, realizing for the first time a single-tube device with up to 110W power output.
With the booming industrial processing market, the power, efficiency and brightness of semiconductor laser chips are facing new challenges, and the improvement of any aspect of laser chip performance will play a huge role in promoting laser applications. Durgan has been in the field of laser chips for many years, and has developed and mass-produced many series of chips, which have been in the leading position in the industry. Through in-depth research on basic physics, material science, chip design and device preparation process, Dewan Core has optimized the chip's internal quantum efficiency, intra-cavity optical loss, and high loading capacity of the cavity surface, and successfully achieved a significant increase in output power and electro-optical conversion efficiency.
The newly developed 915nm 500um width single-tube double-junction laser chip with extremely high electro-optical conversion efficiency has achieved a breakthrough high output power of 110W at room temperature and 55A continuous working condition, which is the leading level in the industry.
