Physics

Scientific paper

A method for creating laser guide stars based on filaments of high-power
femtosecond radiation at altitudes more than 10 km is proposed. The
parameters of femtosecond laser pulses optimal for the formation of
laser guide stars are determined. An analytic expression for the
critical self-focusing power on a vertical path is obtained.
