Investigation of the effects of buffer gas pressure, electrical input power and pulse repetition rate on the output power of a metal vapor laser

Hadi Rahimi, Mahin Darvishi


The effects of buffer gas pressure, electrical input power and pulse repetition frequency on the output power of 510.6nm and 578.2nm transitions have been experimentally investigated in a copper vapor laser with small-bore tube (11mm of diameter and 580mm of length). It is observed that the output power characteristics are strongly influenced by these parameters. A maximum output power of laser is obtained at about 4W with 27 kHz of pulse repetition frequency, 30 torr of Ne buffer gas pressure and 1.42kW of electrical input power. The waveforms of the current, tube voltage and laser pulses have also been observed.
