Apparatus for Shaping of Laser Radiation

An apparatus for shaping laser radiation, the apparatus comprising:

• a shaping substrate formed of one substrate or a plurality of substrates connected to one another, said shaping substrate having a plurality of refractive boundary surfaces formed thereon;
• said boundary surfaces being disposed to allow the laser radiation to be shaped to pass therethrough and said shaping substrate being formed to cause at least two partial beams of the laser radiation that are arranged alongside one another in a first direction prior to passing through said refractive boundary surfaces to be arranged alongside one another in a second direction after passing through said refractive boundary surfaces, wherein the second direction is perpendicular to the first direction.
