Generation of tail-free short pulses using high-pressure CO2 laser
文献摘要：
The spectral linewidth of a transversely excited pulsed CO2 laser is broadened at high working pressures.This phenomenon causes a decrease in the upper-level lifetime such that the pulse width is significantly compressed.Although the tail part of CO2 laser pulses owns a non-negligible proportion of total energy,it has minor effects during the interaction process between photons and materials due to its low amplitude.Thus,it is of great significance to yield the tail part and generate a narrow pulse in most applications.In this study,a continuously tunable pulsed CO2 laser with a low nitrogen proportion in the mixture is developed to generate tail-free short pulses;a minimum pulse width of 30.60 ns with a maximum pulse energy of 481 mJ is synchronously achieved at a pressure of 7 atm,and the estimated peak power is above 15 MW.A numerical simulation is also conducted for comparison with the experimental results.The contribution of the spectral gain toward the compression of the pulse width is discussed in the last section of this paper.
