In tihs paper, we present a method for an one step fabrication process of micro-optical elements in quartz by combining laser induced backside wet etching (LIBWE) and a simple projection method. Micro-optical elements in quartz with continuous structure profiles (e.g. beam homogenizers for high power lasers) are usually fabricated by photolithography, and subsequent transfer of the resist profile into quartz by reactive ion etching.
