Coherent Corp. (NYSE: COHR), a leader in laser and thermoelectric conversion technologies for life sciences and scientific research, has announced the introduction of the OBIS XT, a diode-pumped solid-state laser (DPSS) module that achieves 1000mW output at 640nm for super-resolution microscopy applications. Innovations in visible and ultraviolet lasers have enabled breakthroughs in super-resolution microscopy (SRM), providing critical new insights into polymer structures and cell biology. Coherent has also introduced the OBIS 640 XT, a red laser module that matches the high output, low noise, beam quality, and compact size of its existing portfolio of blue and green laser modules.

Our company, leading the industrial laser market for material processing, has announced the introduction of a new HyperRapid NXT industrial picosecond laser that operates at a wavelength of 532nm and an average output of 100W, enabling ultra-precise manufacturing of thin-film solar cells. The second-generation solar cells, which are expected to achieve a dramatic improvement in energy efficiency, are primarily based on new technologies such as thin-film materials like perovskite and IBC (interdigitated back contact) panels. These new solar cell technologies are increasing the demand for ultra-high-precision scribing and grooving tools that can achieve both electrical contacts within the cells and insulation between the cells in a highly consistent, reliable, and cost-effective manner at very high throughput. With this new laser, manufacturers of second-generation solar panels will be able to respond to increased production volumes while maintaining high quality and low costs.

In December 2020, Coherent Inc. and II-VI Incorporated, both based in the United States, announced a business partnership to strengthen process development and equipment proposals for various welding applications in the automotive manufacturing sector. They will propose advanced laser processing solutions for difficult-to-weld materials such as high-strength steel (high-tensile materials) used in automotive bodies and copper materials commonly used in electric vehicle components. In line with this partnership, Coherent has begun proposing a subsystem that combines ARM fiber lasers with II-VI's RLSK and HIGHmotion 2D processing heads, aiming to maximize productivity on customers' manufacturing lines with this Industry 4.0-compatible solution.

Our company exhibited at the "Photonix 2019 19th Optical and Laser Technology Exhibition" held at Makuhari Messe from December 4 to 6, 2019. A report on our exhibition at this event has been published, so please take a look.

Coherent, Inc. (Santa Clara, California, USA) released its new product, the HighLight DL4000HPR, a compact, high-power, fiber-delivery semiconductor laser system, on June 1, 2018. This model is suitable for metal processing applications such as cladding, thermal processing, and brazing, offering unparalleled convenience and cost performance. The HighLight DL4000HPR features several attractive characteristics for both equipment manufacturers and end users. With its built-in power and control systems, it achieves a very compact footprint and can be mounted in a 19-inch rack. This makes it an ideal model for applications where installation space is a critical requirement, such as in automotive and semiconductor manufacturing environments. Furthermore, the HighLight DL4000HPR uses an indirect water-cooled semiconductor laser, eliminating the need for facilities such as high-purity deionized water or dedicated DI cartridges, making it easy to implement. It also achieves a high conversion efficiency of 45%, resulting in low energy consumption and low operating costs.

Coherent Inc. (Santa Clara, California, USA) announced on May 24, 2018, that it has expanded its product portfolio of industrial laser machine tools through the acquisition of O.R. Lasertechnologie GmbH, based in Düren, Germany. O.R. Lasertechnologie offers compact and high-precision laser additive manufacturing machine tools that support processing systems for cutting, welding, marking, and engraving, as well as Direct Metal Deposition (DMD) and Selective Laser Melting (SLM) methods, which are used in a variety of applications including dental, medical, jewelry, automotive, and aerospace. Thomas Merck, Executive Vice President and General Manager of Coherent's Industrial Lasers & Systems Division, stated, "The integration of Coherent and Rofin-Sinar has been a significant driving force behind our focus on the laser machine tool sector. Furthermore, the products from O.R. Lasertechnologie will further strengthen our solution portfolio in laser additive manufacturing technology."
