Because most nonlinear crystals are birefringent, beams that are collinear inside a crystal may not be collinear outside of it. The phase fronts (wave vector) do not point in the same direction as the energy flow (Poynting vector) because of walk-off. The phase matching angle makes possible any gain at all (0th order). In a collinear setup, the freedom to choose the center wavelength allows a constant gain up to first order in wavelength. … WebFiber Optics and Optical Communications (1) Imaging Systems, Image Processing, and Displays (2) Instrumentation, Measurement, and Optical Sensors (2) Materials (1) Medical …
