In the investigation of the interaction of the intense CW and pulsed CO2 laser with targets, we have studied first the phenomena on targets and observed the forming-time of the crater and the processes of torsion of the direction of the laser plume produced by CW laser. We have also observed the development of the plasma, the air breakdown and the unluminous phenomena such as the plume and shock-wave produced by pulsed laser etc.The device of the framing high-speed interferography with pulsed He-Ne laser was used.
