Abstract : Atmospheric heating by laser pulses in transmission windows has been investigated. Arguments are given for reducing previously given estimates for the absorption in the neighborhood of 10,468 A by nearly one order of magnitude. A study has been initiated of an additional heating mechanism not previously considered, namely collision-induced conversion of laser energy into energy of translational molecular motion. A discussion is given of a classical model and of extensions to a quantum mechanical description. (Author)
