II‐VI Inc has introduced new 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. II-VI’s new pump laser modules achieve 80 W 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 pump laser modules leverage the reliability of II-VI’s gallium arsenide semiconductor laser platform, proven through broad deployments in industrial laser systems and optical networks, and with decades of field operation. Beyond ultrafast fiber-lasers for precision micromachining, II-VI’s product portfolio enables advanced pulsed lasers for other applications including super continuum lasers and excitation sources for life sciences.

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.

II-VI will showcase its broad portfolio of engineered materials, lasers and optics, for materials processing, life sciences, consumer electronics and automotive applications at the SPIE BIOS Expo, San Francisco, CA, Feb. 2-3, 2019, Booth #8543, on biomedical optics and SPIE Photonics West, San Francisco, CA, Feb. 5-7, 2019, Booth #1840, on photonics.
