The summerized results are follows.1. The system utilizing cesium vapor as nonlinear medium, level 6d^2D 3/2 as Two-photon resonant level and difference frequency generation as conversion process will be the most efficient. The result indicates that lowering temperature of cesium vapor cell will be possible by several hundreds degree and it suggests the possibility of realizing a cell based on the principle other than heat pipe oven.2. In the above system collinear phase matching can be realized without any buffer gas according to theoretical calculation. Under the phase match condition the acceptance angle of the system is calculated.3. A secium vapor cell made on experimental basis has been tested and found to be safe. However, the cell permitted the leakage of the vapor, so that the second cell is being constructed.4. Two photon absorption which might restrict the efficiency of the system has been estimated.In conclusion, most of the basic studies on efficient parametric imageupconversion of 10<micrn>m band into the visible wavelength range has been accomplished. The experiment of the image upconversion can be performed shortly.

夏季化结果如下1。该系统利用铯蒸气作为非线性培养基，6D^2d 3/2级作为两光子共振级别，而差异频率产生作为转换过程将是最有效的。结果表明，将降低瓶蒸气电池的温度降低数百度，这表明有可能根据热管烤箱以外的原理实现细胞。2。在上面的系统中，可以根据理论计算而没有任何缓冲气体，可以实现共线相位匹配。在相匹配条件下，计算系统的接受角度3。已经测试并发现根据实验制造的Secium蒸气细胞是安全的。但是，该单元允许蒸气的泄漏，因此正在构造第二个单元。4。结论，两种可能限制系统效率的光子吸收。总结，大多数关于10 <micrn> m频​​段有效参数imageupconversion的基本研究已完成为可见的波长范围。图像上转换的实验很快就可以进行。
