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. … WebOptical fibers usually are specified by their size, given as the outer diameter of the core, cladding, and coating. For example, a 62.5/125/250 would refer to a fiber with a 62.5-µm diam core, a 125-µm diam cladding, and a 0.25 …

WebIn laser science, the parameter M2, also known as the beam propagation ratioor beam quality factoris a measure of laser beam quality. It represents the degree of variation of a beam from an ideal Gaussian beam.[1] It is calculated from the ratio of the beam parameter product(BPP) of the beam to that of a Gaussian beam with the same wavelength.
