A 1hyphen;kpps transversely excited atmospheric CO2laser excited by an allhyphen;solidhyphen;state exciter with a magnetic pulse compressor

摘要

The highhyphen;repetitionhyphen;rate operation of a transversely excited atmospheric CO2laser pumped by an allhyphen;solidhyphen;state exciter consisting of a twohyphen;stage magnetic pulse compressor has been tested. At a repetitionhyphen;rate frequency of 1 kpps, an average laser power of 250 W was obtained. A maximum repetition rate of 1.1 kpps was limited by either the capability of the switching power supply (20 kW) or the turnhyphen;off time of the silicon controlled rectifier used (400 mgr;s). The energy transfer efficiency of the exciter was 75percnt;, and the overall laser efficiency was 3.2percnt;. By changing the amount of the available magnetic flux swing of the cores used, 30percnt; regulation on the input energy was also achieved with a constant energy transfer efficiency of 78percnt;.
