Q-Switched Pulsed Fiber Laser (MFP10W-100W) Series are maintenance-free fiber lasers based on the Q-switched technology and MOPFA. These lasers deliver light centered at 1064nm and guided to the work piece via a flexible metal-sheathed fiber cable. It provides a set of pulse durations, repetition rates and peak powers. The optical head may be equipped with an opto-isolator, that makes it possible to mark directly on non-metallic materials (plastic, wood, paper, etc.) and some metal with low reflectivity.
