SDL-6300 4.0 W CW InGaAs Laser Diodes

Laser diodes in the 910 to 980 nm wavelength range are required as optical pumps for Er+ and Yb+ doped solid- state lasers, such as double-clad fiber lasers. Our new 6370 Series of InGaAs CW laser diodes provides reliable CW power, at 2 W, from a 100 µm aperture. The state-of-the-art 6380 Series laser diodes provide unprecedented brightness and reliability at 4 W, from the same aperture, to power a new generation of emerging products. The fiber-coupled version of this device provides 2.5 W from a 100 µm fiber into 0.16 NA. These unique laser diode products can also be used in medical and materials processing systems.

The SDL-6370 and SDL-6380 are both fabricated using an MOCVD- grown, strained quantum well active region. The 6380 features an entirely new epitaxial design that simultaneously optimizes power, brightness, efficiency, and reliability. The product's inherently high efficiency, together with our unique low thermal- resistance assembly, minimizes junction temperature rise, thereby increasing device operating lifetime. Proprietary device, packaging, and screening technologies ensure the highest reliability available in the industry.

The SDL-6370 or 6380 is offered in our standard, high-reliability "A Block" package. The 6380-L2 is a low-cost, rugged, fiber-coupled package, available with the option of an SMA-type connector or mounting plate.
