Features Q-Switched Pulsed Fiber Laser (MFP20W- 50W) Series are maintenance-free fiber lasers based on the Q-switched technology and MOPFA. These lasers deliver light centered at1064nm 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 anopto-isolator, that makes it possible to mark directly on non-metallic materials (plastic, wood, paper, etc.) and some metal with low reflectivity.No shadow or virtual open circuit phenomenon when processing on special materialsUniversal DB-25 interface;High beam quality fiber output Characteristics Parameters Mode Pulse Beam Quality M² Min. 1.1 /Typical:1.3 / Max.: 1.6 Center Wavelength 1064nm Spectrum Width(3dB) Typical 5nm/ Max.10mm Average Optical Power(Pnom) 20W/30W/50W/70W Power Range Min.10 /Max.100 Single Pule Energy 0.67 mj(20W) / 1mj(30W 50W) Optical Pulse Width(FWHM) 100ns Pulse Repetition Frequency 30~60KHz (20W 30W) /50~80KHz (50W) Output Power Stability Max.5 Beam Diameter 7.5mm Beam Eilipticity Min.90 Delivery Cable Length 2.5 us Laser Startup Time 110~140us Laser Shutdown Time 110~150us Produxt Dimension Standard isolated output head dimensions (unit:mm) Procudt Connection Photos
