Innovator Awards 2023

Laser Focus World Innovator Awards is one of the highest honors in the international laser and optics field. ， It is judged by a professional panel of global industry experts, aiming to recognize various innovative technologies, products, and systems in the laser, optics, and optoelectronics industries, winners are usually regarded as leaders and innovators in the industry. 。

In 2022, Changguang Huaxin participated for the first time with the 30W high-power semiconductor single-bar chip and 680W 976nm 200um fiber-coupled module, winning the gold and bronze awards respectively.

Silver Honoree: 35W Single-Bar Chip

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 directly affect the performance, size, and cost of laser systems.

LFW 2023 Innovator Awards Silver Award

Awarded Product: High-Power Semiconductor Single-Bar Chip

The awarded 35W high-power semiconductor laser chip improves waveguide layer structure optimization, lateral scattering loss structure, and facet protection technology. While maintaining the emission width of 230μm unchanged, the chip output power increased from 30W to 35W, with an electro-optical conversion efficiency exceeding 60%. The high-brightness, high-power, and high-efficiency single-bar chip can significantly improve the output power and price-to-power ratio of fiber laser pump sources, promoting the rapid development of high-power fiber laser pump sources towards miniaturization, lightweight, and intelligence.

2023 New Product

50W High-Power Semiconductor Laser Chip

Changguang Huaxin is committed to providing customers with higher power, smaller size, and higher brightness semiconductor laser chips. In 2023, Changguang Huaxin launched the 9XXnm 50W high-power semiconductor laser chip, achieving 50W laser output within a 330μm wide emission area while maintaining an electro-optical conversion efficiency greater than or equal to 60%. This is currently the highest brightness semiconductor laser chip of the same power known on the market and is now mass-produced and shipped. 。

Bronze Honoree: 1710nm Fiber-Coupled Module

Most polymers exhibit strong absorption for lasers around the 1710nm wavelength. For example, a 1mm thick cyclic olefin copolymer (COC) (used as transparent plastic for medical and automotive electronics) absorbs over 70% of 1710nm laser light. Using lasers in the 1710nm band allows welding of transparent thermoplastics without any additives, with an average efficiency 2 to 3 times higher than traditional welding processes.

LFW 2023 Innovator Awards Bronze Award

Awarded Product: 1710nm Fiber-Coupled Module

Changguang Huaxin's 1710nm fiber-coupled module outputs over 50W through a 400μm / NA 0.22 fiber, with a working current of 16A and a maximum operating voltage of 22V. The working current and voltage meet the requirements of 1710nm fiber laser pump sources. Additionally, the conduction cooling system provides customers with more flexible installation options. The product has passed low/high temperature storage tests, shock vibration tests, and aging tests, including over 6000 hours of aging at 19A working conditions without any degradation.

Changguang Huaxin's 1710nm fiber-coupled module relies on the company's leading intelligent production line for fiber-coupled modules, mature packaging, optical devices, and manufacturing processes. Delivery time and product quality are guaranteed, and the product can be customized according to customer power requirements, boldly pioneering the transparent plastic laser welding application market.
