Power and energy characteristics of continuous waves/pulsed CO 2 laser application in CNG-DI ignition

This work was arranged to develop the scientific database and integrate the application of lasers in high voltage engineering. The design and experimental studies on continuous wave (CW)/repetitively pulsed CO2 laser was carried out in detail to determine the laser characteristics between various design parameters and the effect of varying one parameters on others. The thresholds and steady state input voltage and power across the laser tube are determined. The maximum and minimum output energy and power of the laser system are also presented as function of the pulse repetition rate and discharge current. The CO2 laser system was operated at 10.6 µm wavelengths range of infrared electromagnetic spectrum. This study is presented due to the wide applications of CO2 lasers in industry and for this project for CNG-DI ignition.
