Most Suitable Length of Coaxial Cable to Operate Copper Vapor Laser for Maximum Output Power

This paper aims to study the effects of high voltage coaxial cable (RG 220) parameters on copper vapor laser (CVL) performance. The efficiency of CVL is near about 1% only thus it is strictly required to have most suitable length of coaxial cable to achieve maximum output power. The copper vapor laser is unusual with respect to its high power and high efficiency in this region and in that its normal operation is at pulse repetition rates of several tens of kilohertz. Fast rise time, high voltage pulse to CVL is provided from pulsed power supply through high voltage coaxial cable. As the length of coaxial cable changes its parameters like inductances, capacitances and resistances affects the performance of CVL. Experimental studies will be carried out using 2 m high voltage coaxial cable. The major challenge is to achieve the desired output rise time and high voltage output with required for optimum CVL output.
