Pulsed electrodeless discharges used as laser pumping provide high peak power,high UV content,high optical coupling effieienoy,long life-time and good reproducibility. These unique features seem very promising for high power atomic iodine lasers.A Tw order laser amplifier of 20cm diameter and 8m long pumped by this scheme is proposed. The characteristics of such pumping system are discussed.

以脉冲无极放电作激光泵浦源,可提供高峰值功率、高紫外分量、高光学耦合效率、长使用寿命,并有良好的再现性。这一特点可望用于高功率碘原子激光器。本文提出一个以此种方式泵浦的兆兆瓦级、直径20厘米的激光放大器方案,论述了此种泵浦系统的特点。

The cross sections of deutron-deutron reaction for deutron energy from 15 keV to 150 keV and of deutron-tritium reaction for deutron energy from 13.8 keV to 114.3 keV were measured by the process of passing a deutron and tritium beam into a gas target formed by a differential pumping system and two capillary pipes. Experiments in two steps-angular distribution measurement and absolute differential cross-section measurement-were performed at 3 Cockcroft-Walton generators with terminal voltages of 50 kV,...

The cross sections of deutron-deutron reaction for deutron energy from 15 keV to 150 keV and of deutron-tritium reaction for deutron energy from 13.8 keV to 114.3 keV were measured by the process of passing a deutron and tritium beam into a gas target formed by a differential pumping system and two capillary pipes. Experiments in two steps-angular distribution measurement and absolute differential cross-section measurement-were performed at 3 Cockcroft-Walton generators with terminal voltages of 50 kV, 150 kV and 300 kV. Emperical fit of D-D reaction data to Gamow formulae and comparison of D-T reaction data with BWE theory were given.

采用无窗气体靶技术测量了15—150keV的氘-氘以及13.8—114.3keV的氘-氚反应截面,误差≤±5.1%。实验是分别在50kV、150kV、300kV三台倍加器上进行的。测量分绝对微分截面与相对微分截面测量两步进行。在完成测量数据的实验过程中,相应地发展了氚操作技术与加速氘、束流热测法(量热器)以及对气体的压力、温度、纯度绝对值测量等方面的技术。

In optical pumping system the ~(87)R_b cell is acted by microwave field(f- 6834.6875MHz),We observed the transient state by using an optical detecting method when the microwave had ended.Calculation based on the density matrix theory gives the same results.It also conforms to the model of classical theory.

在~(87)R_b 气室构成的光抽运系统中,加上微波场(6834.6875MH),用光检测方法观测了微波结束时的瞬态。密度矩阵运算结果与实验相符,也与经典力学模型一致。
