The leader of material processing industry lasers, Cohen Corporation, announced yesterday the launch of its new HyperRapid NXT industrial picosecond laser, with a working wavelength of 532 nm and an average power of 100 W, which can achieve ultra precision manufacturing of thin film solar cells.

The second generation solar cells, which are expected to achieve a leap in energy efficiency, are mainly based on new technologies such as thin film materials such as perovskite or cross finger back contact plates. These new solar cell technologies are driving the demand for ultra precision marking and slotting tools, which generate electrical contact within the battery and isolate between cells, with very high throughput and consistent, reliable, and cost-effective approaches. Coherent company is launching a new picosecond industrial green laser based on the on-site verified HyperRapid NXT platform, with 100 μ J's output pulse energy and high beam quality. This new type of laser enables second-generation solar panel manufacturers to meet their production growth requirements while maintaining high quality and low cost.

"We are looking forward to taking a big step forward in this new, exciting, and rapidly growing laser market for processing thin-film solar cells," said Dr. Torsten Rauch, Senior Vice President of Solid State Laser Europe Business Unit. Compared to existing nanosecond lasers or low-power ultra short pulse lasers, our new high-power 532 nm HyperRapid NXT laser meets the market's demand for higher process quality and throughput. Our green laser can produce smoother and cleaner streaks, and has the smallest heat affected zone. More importantly, these lasers are built on the same HyperRapid NXT platform, which has been proven multiple times Reliability, and uninterrupted operation in large-scale manufacturing environments, with on-site verified records.

The new HyperRapid NXT utilizes highly differentiated optical components and crystals manufactured internally by Coherent. The new laser includes all standard features of the HyperRapid NXT platform, including stable power modulation, on-demand pulses, and variable repetition rate. The wavelength range of the laser ranges from ultraviolet to near-infrared, including 266 nm, 355 nm, and 1064 nm. The new 532 nm laser will be officially launched in the third quarter of 2024.

The relevant companies provide support to customers through customized service agreements, which are supported by a global service network composed of factory trained service engineers. Through relevant company laboratories, relevant companies collaborate with customers to predict and solve their most difficult manufacturing challenges.
The related company will showcase its extensive material processing products and innovations at the Photonics West 2024 exhibition in San Francisco from January 30th to February 1st, booth # 4805, and SEMICON Korea booth # C668 in Seoul from January 31st to February 2nd.
