| Abstract: | The problem of relaxation is solved for a thermal lens which has been formed by a short laser pulse in a condensed medium. An expression is obtained for the focal length of such a lens and the asymptotic trend of the focal length as time increases is determined.Translated from Inzhenerno-Fizicheski Zhurnal, Vol. 45, No. 6, pp. 983–987, December, 1983. |
