1940 nm diode-laser arrays

DILAS (Mainz, Germany) has introduced the only commercially available high-power diode laser arrays operating at 1940nm with wall plug efficiencies of >10%. The laser modules are primarily targeted at the medical (therapeutic dermatology and surgery) and industrial markets (material processing applications).

Based on a single diode laser array, the conduction-cooled, fiber-coupled diode laser modules generate output power of 6W, 12W, and 18W, using a standard 600-micron fiber bundle with a numerical aperture of <0.22 and SMA-905 fiber connector. With proprietary epitaxy, these high-power diode laser arrays can be principally integrated into all DILAS packages, ranging from single-bar configurations up to large-scale stack modules which can include hundreds of bars per module.
