摘要： An optical fiber launcher assembly can include a low precision fiber array that outputs a plurality of optical signals from a given side that are input into an opposing side. The optical fiber launcher assembly can also include a corrective optic aligned with and spaced apart from the low precision fiber array. The plurality of optical signals output from the low precision array to the corrective optic have a given trajectory and optical signals output from the corrective optic have a substantially parallel trajectory different from the given trajectory.

摘要： The present invention provides systems and methods for spectral beam combination by applying a spatial chirp to each of a plurality of input beamlets using a respective plurality of dispersive elements and combining the spatially-chirped beamlets into a single collimated output beam using a dispersive element configured to remove the spatial chirp. In an embodiment, each dispersive element is a grating combined with a lens that is confocal to the grating and also confocal to a Fourier plane upon which a transverse distribution of beam spectral components is produced. A final lens-grating pair includes a lens and a grating, where the lens is confocal to the grating and also confocal to the Fourier plane.

摘要： A solid state zig-zag slab laser amplifier in which depolarization occurring at total internal reflection from opposed lateral faces of the amplifier slab is controlled by selecting a complex evanescent coating that provides a selected phase retardance that results in minimization of depolarization. Without use of the complex coating, small changes in incidence angles can result in phase retardance changes large enough to increase depolarization significantly, especially when the amplifier is operated at higher powers. Appropriate selection of the complex evanescent coating allows a desired phase retardance angle to be maintained relatively constant over a small range of angles of incidence, at a given wavelength, and therefore permits minimization of depolarization and birefringence effects.
摘要翻译：通过选择提供选择的相位延迟以导致去极化最小化的复数渐逝涂层来控制在放大器板的相对侧面处的全内反射处发生去极化的固态锯齿形板激光放大器。不使用复杂的涂层，入射角的小变化可导致相位延迟变化足够大以显着增加去极化，特别是当放大器在较高功率下工作时。适当选择复杂的消逝涂层允许期望的相位延迟角度在给定波长的小入射角范围内保持相对恒定，因此允许最小化去极化和双折射效应。
