May 15, 2023 International Laser Industry Conference was held in China Optics Valley Science and Technology Exhibition Center. At the meeting, China's laser industry "Halo Awards" was awarded, Xi'an Lumcore Optoelectronics Co., Ltd. (hereinafter referred to as "Lumcore") 808nm 600W semiconductor laser chip won 2023 "Halo Awards" excellent laser device product Award.
"Halo Awards" was initiated by the well-known optical electronics industry media - Optical wire transfer, and jointly organized by China Laser Magazine, a first-class publishing institution in the field of laser, optics and photonics. "HALO Awards" is composed of the first letters of four English words such as Honor, Accumulation, Leadership and Openness. It aims to commend truly valuable optoelectronic products, technological innovation, or subversion of ideas, with professional and objective uation. Or the breakthrough of the process, in order to establish the concept of enterprise innovation first, leading the innovation boom of photoelectric enterprises.
808nm 600W semiconductor laser chip
• Product description
The product has the characteristics of high output optical power, high electro-optical conversion efficiency, good beam quality, high reliability and compact structure, and is widely used in advanced manufacturing, medical cosmetology, aerospace, entertainment display, security protection and other fields.
• Product features
Through the research on the key technology of 808nm quasi-continuous 600W semiconductor laser chip, the core technology of 808nm quasi-continuous laser chip has been obtained, and significant progress has been made in the structure optimization technology, material epitaxial growth technology, cavity surface passivation technology and packaging technology, which solves the key problems of 808nm quasi-continuous laser chip in the production.
• Innovation and breakthrough
The epitaxial structure is upgraded, while the basic parameters such as slope efficiency and conversion efficiency of the chip remain unchanged, the high temperature characteristics are greatly improved. The reliability of the chip is improved by upgrading the key equipment that affects the life of the device, reducing the residual gas that affects the reliability of the chip. Through the optimization of the surface coating process, the surface damage threshold COMD of the chip has been improved, and the optical power density of the device in stable operation has been increased from 10MW/cm2 to 14.23MW/cm2.
The award of this honor is the industry's recognition of the overall technical strength of Lumcore. Lumcore will continue to practice the enterprise mission of "establishing the source of China's core laser", adhere to independent research and development, work hard to break through the bottleneck, and help promote the localization and industrialization of high-end semiconductor laser chips.
