Abstract
International audienceA 100 W copper “HyBrID” laser (CuHBr laser) fitted with an unstable cavity is examined in the far field and compared with a conventional copper vapor laser of similar beam dimensions. In the far field the divergence is about 100 μradians for the HyBrID laser. The copper vapor laser produces a slightly larger central divergence with significant high divergent structure. This is explained to be due to pulse shape and differences in radial variations of the gain onset timing of the two types of laser, improved beam quality is important for efficient pumping of titanium sapphire lasers and micromachininKeywords
