本文报导双脉冲氯化铜激光器参量的研究。研究了激光胠量密度和双脉冲放电的三个特微时间(最小、最大和最佳延迟时间)的有效变化范围。激光器的几何尺寸变动范围包括直径从2.3mm到40.长度从3cm到60cm。在压强为0.5(?)到50(?)范围内,研究了He、Ne、Ar三种缓冲气体的作用。放电管的温度从270℃变到500℃,分介脉冲和泵浦脉冲的能量密度分别从8.5千伏时的不到1mJ/cm~3变到20千伏时的超过500mJ/cm~3。我们发现获得最大激光能量密度的最佳条件是:在温度为400℃,长30cm,直径10mm的激光管中充于20(?)氖,获得的最大能量密度为22μJ/cm~3。
This paper reports the research of the parameters of double pulse copper chloride laser. The effective range of the three special times (minimum, maximum and optimum delay time) of laser density and double pulse discharge was studied. The geometric range of the laser varies from 2.3 mm to 40 in diameter and from 3 cm to 60 cm in length. In the pressure range of 0.5 (?) To 50 (?), Studied He, Ne, Ar three kinds of buffer gas role. The temperature of the discharge tube was changed from 270 ° C to 500 ° C, and the energy density of the separation pulse and the pump pulse were changed from less than 1 mJ / cm 3 at 8.5 kV to 500 mJ / cm 3 at 20 kV. We found that the best laser energy density obtained is that the maximum energy density is 22μJ / cm ~ 3 when filled with 20 (?) Neon in a laser tube with a length of 30cm and a diameter of 10mm at a temperature of 400 ℃.
