In recent years, in the medical beauty market, Shandong Huaguang Optoelectronics Co., Ltd. 808nm semiconductor laser technology relies on its good unity, better penetrating power, selective photothermal action, safely, quickly and efficiently removes any part of the human body and Many advantages such as deep hair have become one of the mainstream hair removal technologies, and 808nm semiconductor lasers have developed rapidly in the field of hair removal. Should be increasing market demand, Huaguang Optoelectronics Co., Ltd. relies on 19 years of experience and technology accumulation in high-power semiconductor laser epitaxial design growth, chip fabrication, device packaging, and introduces long-life, high-reliability, gold-tin package macro channel Semiconductor laser module, power coverage 300W, 500W, 1000W. At present, the monthly production capacity has reached more than 1,000 units.
This series of module packaging technology adopts the research results of Huaguang Optoelectronics strategic project and passed the identification of Shandong Province information technology and information technology achievements. The maximum output power of 300W, 500W, 1000W macro channel modules under continuous current test is 360W, 750W, 1200W, respectively. The corresponding energy is far beyond the requirements of hair removal application, and the wavelength-current drift coefficient is 0.15nm/A, which has reached the industry. Leading level.
According to the needs of customers and practical applications, Huaguang Optoelectronics can provide a cost-effective beam shaping solution for the series of green laser pointer laser modules to achieve square spot output and improve energy density and uniformity distribution.
As the core component of the laser module, the localization is low. Most of the modules on the market use imported bars. The supply and delivery cycle cannot be guaranteed. In particular, the recent ban on the supply of chips for ZTE in the United States is even more China's semiconductor industry is shocked by a cold sweat, so to prevent similar incidents from happening again, Huaguang Optoelectronics used self-produced 100W and 60W bars in this series of laser module products (refer to Figure 4), which is sourced from Huaguang Optoelectronics. National 863 Project - High power 808nm asymmetric aluminum-free strained quantum well laser results transformation. The output power of 100W bar is 142W@135A under continuous current test, the slope efficiency is 1.16W/A, and the electro-optic conversion efficiency is 50% (refer to Figure 5, it can be seen from the figure that the output light power of the bar at 135A current is There is no obvious thermal saturation, but it is limited by the current carrying capacity of the power line, so it has not been tested.) The core technology of the 863 project provides a strong guarantee for product quality and supply capacity.
The high-tech semiconductor laser module for medical beauty developed by Huaguang Optoelectronics has excellent performance and has been successfully introduced to the market. It has taken a solid step on the road of localization of high-power chips. Huaguang Optoelectronics Co., Ltd. is committed to research and development. High-power chips and bars with higher power and higher power, and put into use on laser devices, leading the trend of domestic production of chips and laser devices.
