The Green Laser is easy to recognize - it produces a visual light of light green color. The wavelength of the laser, also known as the green laser, is 532 m. It does not generate heat and is therefore referred to as a cold laser or cold marking laser. The Green Laser is often used in the field of laser marking with sensitive surfaces. For example, cold marking lasers can be used for optimal processing of plastics. Another outstanding feature of a green laser is its high stability and beam quality. For materials that cannot be marked optimally with a conventional 1064 nm wavelength laser (fiber laser), the green laser is the solution.
