Paper Abstract

Methods of reformatting the output of laser diodes and maintaining much of their intrinsic brightness are discussed. A commercial, fiber-coupled package is shown with a symmetric etendue and a brightness of 15 kW/(cm2 sr). A symmeterized beam with a brightness of 200 kW/(cm2 sr) is demonstrated by using a combination of a micro-lensed diode array and a lens array.
