LASER COMPONENTS offers a range of beam expanders for YAG systems and other wavelengths, used primarily for increasing laser power densities at the focal point, and beam guidance over long distances.

Available in versions providing a fixed or zoom expansion factor, a family of laser beam expanders is designed for 355-nm light at up to 100 W (cw). With an 8-mm input aperture and a 22-mm output ...

Optical Surfaces Ltd. has announced its reflective beam expanders are now available with the option to optimally operate in high vacuum environments, expanding or reducing high power laser beams.

density in the focal point by increasing the beam diameter before the focussing lens, and reducing the beam divergence through beam expansion which is useful for beam guidance over long distances ...
