DLR-976, 100-1500 W

Diode Laser Rack-mounted Units

DLR-976 Series are high brightness diode lasers featuring wavelength stabilized narrow-line diode-to-fiber combining of highly reliable entirely sealed single-emitters. These industrial grade fiber-pigtailed diode lasers are available at powers up to 1.5 kW and have a wall-plug efficiency approaching 35%. DLR-976 diode laser is brighter, higher quality and more reliable than any other diode laser on the market. Air or water-cooled, this compact platform is cost-effective and virtually maintenance-free. DLR-976 lasers are used in soft soldering, metal hardening, plastics welding, silicon surface modification and FPD bonding, and are also an ideal source for optical laser pumping.
