Two-mirror beam-shaping technique for high power diode bars
Two-mirror beam-shaping technique for high power diode bars
A simple beam-shaping technique is described whereby the output from a highly asymmetric, non-diffraction-limited laser source, such as a high power diode bar, can be reconfigured with nearly equal beam quality factors in orthogonal planes and without a significant reduction in brightness. Using this technique, in conjunction with conventional lenses, the output from a 20 W cw diode bar has been focused to a very intense, nearly circular, spot with a 1/e2 beam diameter of ~100 µm and a far-field beam divergence (half-angle) of ~0.2 rad.

Abstract
A simple beam-shaping technique is described whereby the output from a highly asymmetric, non-diffraction-limited laser source, such as a high power diode bar, can be reconfigured with nearly equal beam quality factors in orthogonal planes and without a significant reduction in brightness. Using this technique, in conjunction with conventional lenses, the output from a 20 W cw diode bar has been focused to a very intense, nearly circular, spot with a 1/e2 beam diameter of ~100 µm and a far-field beam divergence (half-angle) of ~0.2 rad.
