Product Overview:

915nm, 70W Laser Diode Overview:

Key features of these devices include a high output of 70 watts, center wavelength of 915nm, and a 105µm fiber core diameter. They also have 1040nm-1200nm feedback protection. These laser diodes 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 915nm 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. Laser pumping, material processing, and an array of applications in the medical field are the common uses for these lasers.
