Fiber Coupled 976nm 85w High Power Diode Lasers High Efficiency For Laser Pumping


 
BWT Beijing's High Power Diode Laser Modules are manufactured by adopting specialized fiber-coupling techniques, resulting in volume products with a high efficiency, stability and superior beam quality. The products are achieved by transforming the asymmetric radiation from the laser diode chip into an output fiber with small core diameter by using special micro optics. Inspecting and burn-in procedures in every aspect come to a result to guarantee each product with the reliability, stability and long lifetime.
Our research staffs are constantly improving and innovating the processing technology in the producing process, based on the professional knowledge and experience accumulated in long-terms. We are also continuously developing new products to meet customers' specific needs.
At BWT Beijing, to provide high quality products with reasonable price is our always goal.

 
Introduction:
 
Besides the conventional diode laser, BWT has narrow linewidth series at 976nm, the output power 3W, 9W, 25W,50W, 60W and 85W. The laser power from fiber-coupled modules is delivered via a non-detachable fiber core which is terminated with a standard SMA-905 fiber connector. With VBG frequency-selecting and excellent heat removal, this industrial package is ideal diode laser for laser pumping.
