Refractive-diffractive hybrid lens, in particular for beam shaping of high power diode lasers

A cylindrical lens having a refractive optical element and a diffractive optical element is provided. The cylindrical lens can be fabricated cost effectively and precisely, and optical aberrations and defects in semiconductor diode laser arrangements can be corrected. The diffractive optical element...
