The optical constants of two cyanine dye films we prepared have been measured by a RAP 1 typed spectroscopic ellipsometer. On the basis of making a simplified model for the wafers of a recordable compact disk (CD R), the optimizing designs for them developed by the cyanine dye films are given. In addition, the dynamic storage performances of two sample disks have been tested by our dynamic storage testing system. Measurement results of the sample disks are obtained to test our film designs.

The effective reflection area of a cube corner retroreflector is defined. It is testified for a cube corner retroreflector (CCR) that the ray reflected from a CCR is not parallel with the ray incident on the CCR undersurface. The effective reflection area of CCR is calculated when the ray incident on the CCR undersurface vertically, and the effective reflection area of a CCR is two thirds of the CCR undersurface.

It is reported a novel optical parametric oscillator with KTP as medium crystal inside a Nd∶YAG phase conjugate resonator. In the phase conjugate resonator, the laser beam quality is promoted by phase conjugate mirror, which is realized by stimulated Brillouin scattering effect, and Q switch is generated simultaneously. With this device, the laser output at 1.57 μm with 15 mJ energy and 8 ns pulse width is obtained.

The 2 MeV energy He＋ ion implantation for constructing planar optical waveguide in tunable laser crystal Ti:Al2O3 was performed. Lattice damage by ion bombardmentwas investigated by means of optical and SEM studies, different damage depths of about 5 μmand 10μm for Al-sublattice and O-sublattice of the Ti:Al2O3 substrate were obtained by electron probe microanalysis (EPMA).

用晶格气体模型系统地研究了１２９Ｘｅ热发射体的轻粒子、带电粒子和中间质量碎片的发射特性，发现了在温度５ —５５ＭｅＶ区间，以上物理量的平均多重性和发射源的最大碎片余核及源的热激发能随温度变化的斜率存在着各自的峰值，同时它们的分布宽度（即涨落）也存在着最大值．进一步研究发现在５ —５５ＭｅＶ区间，这些宽度随温度的变化的斜率显示了明显的不连续性．所有这些特征说明了在５ —５５ＭｅＶ的拐点温度处，最大的临界涨落是自发地伴随着相变和临界现象．
