A new technique is presented whereby CO2 laser pulse length control can be achieved at wavelengths near 10 µm. A doubly truncated pulse shape is produced by transmission through and reflection from laser induced breakdown plasmas. The method by which the length of the pulse may be varied is described and evidence is produced for useful spatial quality of the output beam. © 1978.
