The Q-switched marking and precision-machining device PERPETUUM™ represents the world’s first hand-held, high power laser. By virtue of its unique concept the system is wearable, battery-powered and operates always in laser class 1. With rechargeable battery package in a size of a human fist, it generates in the pulsed standard version up to 10W (CW) infrared beam (1064nm) or alternatively a 5W (CW) green laser beam (532nm), resulting in several hours of processing-time in production practises.
