CRD Laser successfully developed an optical lens with a wavelength of 9.3µm in 2016, injecting core technological impetus into the laser processing industry. This lens precisely fits the 9.3µm band CO2 laser, not only achieving stable laser oscillation and output, but also reshaping industry standards with outstanding marking accuracy - whether it is the fine lines of automotive parts or the complex markings of electronic components, it can present a micron-level clear effect, significantly improving the processing quality in the 3C electronics, new energy and other fields.

In 2021, CRD Laser successfully achieved stable emission of 9.6µm wavelength laser, which is the most difficult for CO2 lasers to output, with its dual-lens combination screening technology. This breakthrough was hailed by industry experts as a "key milestone in the field of mid-infrared lasers".
