An experimental electrical parameter measuring system for an asymmetric capacitive radio frequency discharge excited copper ion laser

摘要

An experimental system has been designed and built to study the electrical characteristics in an asymmetric capacitive coupled radio frequency (RF) discharge excited copper ion laser at moderate gas pressures. The system consists of laser chamber, thru-line integrated voltage and current probe, matching circuit and electrical measurement system. There are some results of electrical measurements carried out in a helium discharge at 13.56 MHz. Although this system has been specifically designed and built to measure the discharge parameter of the capacitive RF-excited copper ion laser in moderate-pressure helium gas, it can operate over a wide range of gas pressure and a wide range of driving frequency and gas components. It is simple, cheap, accurate and real-time. [References: 11]
