Changguang Huaxin high-power laser chip breaks through 66W
03/01
2023
High-power, high-brightness semiconductor laser chips are the cornerstone and source of the laser industry chain. The power, brightness, and reliability of laser chips, as core indicators, directly affect the performance, size, and cost of laser systems, and are the premise and guarantee for achieving miniaturization, lightweight, and intelligence of laser systems. Changguang Huaxin is committed to the research and production of higher power and higher brightness single-bar chips. Recently, the power of single-bar chips has breakthroughly reached 66W. 。
In January 2023, at the Photonics West 2023 conference, we first reported that under the condition of maintaining brightness (chip bar width 230μm), the chip output power increased by 20% (power increased from 32W to 40W), with a maximum power exceeding 51W. The power-brightness performance of this chip is the highest level known for high-power laser chips with a 230μm bar width.

Changguang Huaxin continuously explores to achieve sustained improvement of chip power under high brightness conditions.
In February 2023, based on the chip technology reported at Photonics West, our company developed a higher power wide-bar semiconductor laser chip, Changguang Huaxin launched the industry's first single-bar chip with a maximum power exceeding 66W. (Heat sink temperature at room temperature), chip bar width 290μm Maximum efficiency exceeds 70%, operating efficiency exceeds 63%, which is the highest level known for high-power laser chips with a bar width below 400μm to date.

Stay true to the original aspiration and forge ahead. Changguang Huaxin will continue to focus on the breakthrough and technological innovation of semiconductor laser chips, always maintaining chip power and brightness at the industry forefront level, and tirelessly strive for Chinese laser chips to illuminate a better life!
