Abstract (en)

[origin: WO2006074681A1] The invention relates to a device for altering the intensity distribution of a laser radiation field, comprising two substrates (3, 4) with differing refractive indices (n<SUB>2</SUB>, n<SUB>3</SUB>) and with two opposed, mutually corresponding optical functional boundary surfaces (5, 6), which are at least partly curved. The laser radiation field for altering can pass serially through the optical functional boundary surfaces (5, 6), whereby the difference (?n) in the refractive indices (n<SUB>2</SUB>, n<SUB>3</SUB>) of the first and second substrate (3, 4) is less than 0.1 and the cavity (9), between the first optical functional boundary surface (5) and the second optical functional boundary surface (6) is embodied such that the laser radiation, on propagation from the first substrate (3) into the second substrate (4), is essentially subjected to one refraction on the basis of the difference (?n) in the refractive indices (n<SUB>2</SUB>, n<SUB>3</SUB>) of the first and second substrate (3, 4).
