Laser Beam Splitting by Diffractive Optics

Recent advances in diffractive optics theory and technology have made it possible to design programmable, multichannel optical systems based on diffraction gratings, lenslet arrays and digital holography algorithms. Spot array generation, multiple and multifocal imaging, matched filtering, laser beam mode selection and simultaneous contour shaping are among the most promising applications of diffractive beam splitting.
