摘要：
An array of seven fiber collimators with transmission similar to 99.9% was tested with 1.99 kW per channel. Truncated radiation was disposed through output collimating lenses by re-directing Gaussian beam tails with interior holey micro-lenses. For range of truncation of 5-29% cooling was not necessary. Beam quality in the far-field M-2 similar to 1.2.
