title: A lézerfény terjedésének vizsgálata a katonai lézertechnikai eszközök alkalmazásának tükrében
abstract: Results of different disciplines in context to directed energy weapons can not be easy undertaken.I have restricted the area of my research onto laser light propagation investigation, using my previous results and experiences.It isn't known such optical media, that do not affect the light propagations.It can be assumed that propagation of light in thermally stabilized and reduced pressure chamber (vacuum) in a straight line, but otherwise not.Based on the foregoing it follows, that influence of
