In this paper, we propose and demonstrate an adjustable-free and movable thin disk laser based on the telecentric cat’s eye cavity. We design a V-shaped laser cavity containing two reflectors with thin disks as the gain medium. The experimental results from the traditional plane-plane cavity, plane-telecentric cat’s eye cavity, and double telecentric cat’s eye cavity are compared. They show that plane-telecentric cat’s eye cavity laser can keep operating at the adjustable-free range of to , which is up to 60 times better than that of traditional plane-plane cavity. In the double telecentric cat’s eye case, the adjustable-free range is improved to to . Additionally, in the case of the double telecentric cat’s eye cavity, the output telecentric cat’s eye can achieve free movement within the horizontal range of .

Square microcavity laser with an output waveguide is proposed and analyzed by the finite-difference time-domain (FDTD) technique. For a square resonator with refractive index of 3.2, side length of 4 microns, and output waveguide of 0.4-micron width, we h
在早期的研究中,采用出、入瞳直径相等的双通系统进行人眼像差测量时,两个通道的奇像差相互抵消,造成奇像差(如彗差)无法测量。本文建立全新的模拟眼模型进行实验,验证双通系统在波前测量时,是否存在人眼奇像差抵消的现象。采用典型双通系统——哈特曼波前探测系统进行实验,并将出瞳光阑直径固定为6mm,改变系统入瞳光阑大小(1~8mm)。实验结果表明,双通系统中,人眼奇像差在出、入瞳直径相等时可测,且人眼奇像差
Photodynamic therapy (PDT) has become an attractive tumor treatment modality because of its noninvasive feature and low side effects. However, extreme hypoxia inside solid tumors severely impedes PDT therapeutic outcome. To overcome this obstacle, various
光将声波加以放大,这是第一次,方法是将一束激光打到一块双折射石英晶体上,在晶体内部是超声回波。从示波器上所显示的线条看出,光将声波放大了大约十倍。
以结构参数的最优匹配为设计目标, 提出了一种改善光学卫星振动环境的新思路。针对某光学卫星振动试验中出现的蜂窝顶板随机振动响应过大的问题, 研究了加强肋在降低简支蜂窝板随机振动响应中的作用。分析了该光学卫星蜂窝板结构的特点, 探讨了它的随机载荷以及在其激励下蜂窝板式结构的动力学响应。结合卫星自身结构上的需要, 提出了一种通过添加特定截面H型加强肋的方法来降低蜂窝板的响应。利用有限元法对外形尺寸为1 000 mm×1 000 mm×30 mm的蜂窝板模型进行随机振动分析验证, 结果显示: H型加强肋能显著降低
