This book addresses the theory and practice of every important technique for lossless beam shaping. It provides experimental results as well as guidance on when beam shaping is practical and when each technique is appropriate, describes the latest advances in beam profile measurement technology and laser beam shaping using diffractive diffusers, and includes new chapters on axicon ring generation systems, laser-beam-splitting (fan-out) gratings, vortex beams, and microlens diffusers. It also contains new material on wavelength dependence, channel integrators, geometrical optics, and optical software.
