Abstract
In this research work, single mode operation based on injection of a CW laser beam into a TEA CO2 laser cavity has been demonstrated. The technique has vast applications in research programs of laser spectroscopy and optical pumping. The observed smooth pulse shapes indicated that the system is operating in a single mode of operation. In addition, the output energy has not been reduced with the laser was operating in a single mode operation on comparison with the case when it is operating in a multi mode regime. Also, no PZT mounted elements or other length stabilization methods were used in order to frequency matching of master and slave resonators.
