WA3.2 - Multi-kW, Uncooled Densely Packed Fiber Array for Laser Beam Combining

Abstract

Abstract

The array of seven fiber collimators with transmission about 99.9% was tested with 1.99kW per one channel. Truncated radiation, ~6%, was disposed through output collimating lenses by re-directing Gaussian beam tails with interior holey micro-lenses. No cooling was necessary. Beam quality in far-field M2 ~1.2.
