چکیده انگلیسی
In a longitudinally excited CO2 laser that had a 45â¯cm-long discharge tube with a 1:1:2 mixture of CO2/N2/He gas at a pressure of 3.0â¯kPa, we realized the generation of a short laser pulse with a spike pulse width of about 200â¯ns and a pulse tail length of several tens of microseconds, control of the energy ratio of the spike pulse part to the pulse tail part in the short laser pulse, the generation of a long laser pulse with a pulse width of several tens of microseconds, and control of the pulse width in the long laser pulse, by using four types of excitation circuits in which the capacitance was adjusted. In the short laser pulse, the energy ratio was in the range 1:14-1:112. In the long laser pulse, the pulse width was in the range 25.7-82.7â¯Î¼s.
