BLM and BLR, up to 1 kW

Blue Diode Lasers

BLM and BLR Blue Diode Lasers provide up to 1 kW continous wave or long pulse mode at ~450 nm to serve a wide range of applications including entertainment, medical, laser pumping and materials processing. Conduction-cooled modules are available up to 50 W, force air-coooled modules up to 150 W power, and water-cooled modules up to 300 W. The BLM modules feature standard SMA-905 connector and can be offered with a range of output options including collimator or bare fiber termination. Compact rugged BLM modules are attractively priced for OEMs and integrators. BLR lasers are water-cooled turnkey diode systems with integrated driver electronics offering standard power up to 500 W with higher output powers available upon request. The BLR lasers feature QBH compatible output connector with 450 μm core fiber and NA of 0.2.
