"E"为光能；"h"为普朗克常数，表示光的粒子特征；"υ"为光的频率，表示了光的波的特征。

The invention relates to a light pumping system for all-solid laser, particularly a light pumping system for disc type laser, comprising heat sink, laser crystal, optical fiber, plane reflector, a first concave reflector, a second concave reflector, and a third concave reflector, and adopting a structure that the plane reflector is between the optical fiber and the first concave reflector, to make the LD and laser cavity on the same side of the laser crystal, thus reducing the packaged size of the laser; the invention fixes the plane reflector on the heat sink to reduce the inclined incident angle of the pumped light beam, thus the pumped light can be fully absorbed, and the invention solves the problem of pumping efficiency and largely reduces the bulk of the laser, beneficial to the all curing of the product and ensuring the cooling requirement of the laser crystal.

本发明涉及全固体激光器的光泵浦系统，特别是一种盘式激光器的光泵浦系统。包括热沉1、激光晶体2、光纤3、平面反射镜4、第一凹面反射镜5、第二凹面反射镜6、第三凹面反射镜7，本发明采用平面反射镜位于光纤与第一凹面反射镜之间的结构，使LD和激光腔位于本发明激光晶体的同一侧，从而减小了激光器的封装尺寸；本发明将平面反射镜固定在热沉上，使泵浦光束斜入射角减小，泵浦光则能充分吸收，为此，本发明解决背景技术采用第一凹面反射镜使泵浦光束斜入射角过大引起的像散，泵浦光斑变形引起泵浦效率降低问题，使得本发明可选用大面积半导体制冷器，避免使用水冷，则激光器的体积大大减少，有利于产品的全固化，保证了激光晶体的散热要求。

报道以一维平面阶梯条形纯位相结构，用等光程补偿的物理概念出发，计算了单线与双线象的衍射光学元件的多种构形，获得了与理想衍射线象符合的光强分布；同时发现双线象时会出现噪音光强小峰，这在精确成象时仍是要设法避免的。

The light sources of edge-type LED backlight units in small/medium displays are an array of LEDs located inside a lamp reflector and near the incidence plane of a light guide plate.

中小尺寸LED背光模组发光源为置於侧边之复数个LED点光源，其所面临的固有问题在於入光侧容易产生明暗不均，亦即导光板在靠近LED光源处会出现过之投灯亮带而在LED之间则容易形成较暗之暗区。

Because the optical system of optical characteristics and the nature of the launch of the optical microscope is not the true meaning of the linear shift-invariant systems, the PSF is usually perpendicular to the optical axis in the xy plane was the distribution of radial symmetry, but the direction along the z axis significant expansion.

因为光学系统的特点和发射光的性质决定了光学显微镜不是真正意义上的线性移不变系统，所以PSF通常在垂直于光轴的x-y平面上呈径向对称分布，但沿z光轴方向具有明显的扩展。

It is verified first that Buckingham and Parlett's perturbation theory on the light-induced energy change of a polarizable atom or molecule is consistent with that of the optical-pumping theory.

鉴于已有的理论孤立地研究Warren等人的实验结果，忽视了与ac Stark效应的关联，我们第一次理论证明了：Buckingham与Parlett的关于在光场的作用下原子和分子的能级改变的基本公式，实际上与光抽运过程中能级光移动的理论相一致。

The split between the two groups can hardly be papered over.
