Recently, the 2024 Laser Focus World Innovators Awards were announced, Changguang Huaxin has won consecutively for three years, with the 50W high-power semiconductor single-chip and the 100W 1710nm direct semiconductor laser winning the silver and bronze awards respectively. 。
International Award Laser Focus World Innovators Awards
The Laser Focus World Innovation Award is one of the highest honors in the international laser and optics field, judged by a professional panel of global industry experts, aimed at recognizing various innovative technologies, products, and systems in the laser, optics, and optoelectronics industries. Awardees are usually regarded as leaders and innovators in the industry. Changguang Huaxin has been deeply engaged in the semiconductor laser field for ten years, winning this award three times in a row fully reflects the company's innovation capability and leadership position in the industry. 。
High-power semiconductor single-chip is the core component of lasers; its power, brightness, and reliability directly affect the performance, size, and cost of laser systems.
Changguang Huaxin focuses on scientific research and development of semiconductor laser chips, and over more than ten years, has released multiple internationally leading breakthrough results. It has made outstanding contributions to the localization of high-power semiconductor laser chips.
The awarded 50W high-power semiconductor single-chip was launched in May 2023, with a wavelength of 9XXnm, stripe width of 330μm, featuring high power, high efficiency, high brightness, high beam quality, and long lifespan, and has been supplied to the market in batches.
Higher power remains the industry's focus, representing the development level of comprehensive chip technology. In January 2024, Changguang Huaxin achieved a breakthrough of continuous 100W single-chip operation, with 62% working efficiency and a 50% power increase, ushering in a new era of hundred-watt single-chip. This promotes the development of pump sources towards miniaturization, lightweight, and intelligence.
1710nm is suitable for welding transparent and white plastics.
Most transparent plastics have absorption peaks near the 1710nm band. At the 1710nm and 2000nm laser bands, transparent materials such as PMMA and PC have low transmittance and laser absorption rates exceeding 70%. Laser absorption rate is closely related to welding efficiency and quality.
Efficient welding with beautiful weld seams.
The 1710nm laser can achieve direct welding, producing minimal stress during welding and requiring no flux or other consumables. The laser beam distribution is uniform, welding quality is excellent, welding is efficient without damaging the upper material, does not alter the material's nature, and does not affect biocompatibility, which is very important in the healthcare industry.
Diverse welding processes.
Various welding processes can be designed according to actual needs (welding of different sized component contours, rotary welding of cylindrical components, welding of small and medium-sized components, surface welding or mask welding), and no maintenance costs are required.
The 100W 1710nm laser is sufficient to meet most plastic welding applications.
The output power of the 1710nm laser does not need to be at least 100W like 808nm and 980nm lasers; generally, tens of watts of optical power can meet most application scenarios. It is an ideal tool for medical plastic instruments, white home appliance plastic parts, automotive plastic parts, or other similar products.
