Patent ID: 8767304

Claim:
A beam shaping device rotating each of incident light beams and, hence, altering a size-divergence product (SDP) in lateral and longitudinal directions, the beam shaping device comprising: a polarizing beam splitter (PBS) interface, for passing light beams in P polarization and reflecting light beams in S polarization; two light input/output (I/O) surfaces, one being perpendicular to the incident light beams and another being perpendicular to light beams that leave the PBS interface; two light surfaces for processing (LSFPs), one being perpendicular to light beams passing the PBS interface and another being perpendicular to light beams reflected by the PBS interface; and each of the LSFPs arranged to retro-reflect back, or close to retro-reflect back the incident light beams; wherein the PBS interface, the two light I/O surfaces, and the LSFPs are integrated into one piece, so that the light beams in the beam shaping device are total internal reflection.
