Nonlinear light source including a device and the device extends the nonlinear optical system of life is exposed to radiation of a strong laser beam

摘要

Be exposed to radiation present invention relates strong laser beam, there is provided an apparatus extends the life of the frequency conversion nonlinear optical system at least one can be converted into an output beam of the optical frequency ω ₂ the incident beam of the fundamental light frequency ω _1. Relates to a device to extend the life frequency conversion nonlinear optical system exposed to the radiation of a strong laser beam (19) The invention relates to a flat and parallel and inclined to the beam the nonlinear optical system (19) two plates having a surface, such as (2,3), the inclination angle range of the first plate 1 _(i^{2 0} ± for δi ₂₎ to move the incident beam optics relative to (19), while minimizing the amplitude of the movement (37, 47) output beam angle range _(i^{2 0} ± and a means for rotating the horizontal (2, 3) of the plate that is suitable to change the inclination angle of the first plate in δi ₂₎ inside. On the application of the device to the non-linear light sources, including non-linear crystal to one or more (1, 16) also invention. [Selection Figure 6
