II-VI Incorporated announced the introduction of its 976 nm pump laser modules with up to 80 Watts of wavelength-stabilized output power. Pump laser modules with wavelength-stabilized output power enable ultrafast fiber lasers to operate with very short pulses for high precision drilling and marking. The company's new pump laser modules achieve 80 Watt of output power, 4 times greater than the existing product, enabling fiber lasers to generate high power levels with fewer modules and lower their cost. The wavelength-stabilized optical design within the module minimizes warm-up time, and operates over a wide temperature range, improving laser system productivity and reducing maintenance. The high output power of the new pump laser is achieved by combining multiple pump laser diodes into one module. The combined output power is coupled to an industry standard 106.5 µm core fiber. The operating wavelength can be adjusted to meet specific customer applications.
