【 摘 要 】

One-dimensional model of a continuous optical discharge is proposed, allowing the estimation of its parameters in a converging laser beam taking into account the refraction of the radiation on the discharge. The influence of spherical aberrations of a focusing lens on the measured thresholds of maintenance of the discharge in the laser plasmatron mode has been discussed.
