| 摘 要： | 采用改进的溶液浇铸法，用氘代聚乙烯为原料,制备了厚度为100, 200, 400 μm的氘代聚乙烯薄膜。研究了溶液温度、干燥温度、真空加热温度及时间等因素对成膜性、薄膜均匀性和透明性的影响，确定了最佳工艺条件:溶液温度120～130 ℃，干燥温度80～100 ℃，加热温度120 ℃，加热时间1 h。3维视频显微镜和原子力显微镜表征结果表明:制备的薄膜透明性较好,厚度较均匀;薄膜表面起伏较小。

| Abstract: | A long-pulse TE CO2 laser with ultraviolet-preionization using pulser/sustainer discharge technique is presented. The laser can discharge stably with 14 nF pulser capacitance and 200 nF sustainer capacitance by optimizing the parameters of pulse forming network and amending the Chang’s profile. For an active volume of 2.48 L, a gas mixture ratio of CO2, N2, He is 1∶2.5∶13 and the gas pressure of 40 kPa, the maximum output laser energy of 18.51 J with a pulse width of 32 μs is obtained at an efficiency of 14.3%. |
