INFLUENCE OF THE ATOMIC MASS OF A PLASMA-FORMING TARGET ON THE PARAMETERS OF LASER-EMISSION DISCHARGE
V. V. Shkurko UDC 621.378.9 A study has been made of the influence of the atomic mass of the material of a plasma-forming target on the characteristics of a laser-emission discharge developing under the action of Nd-laser radiation on the target. It has been shown that the atomic mass substantially affects the efficiency of conversion of the energy of laser radiation to the energy of a quasistationary electric current; the behavior of the dependences of the load power on the atomic mass of the target substance is different for high vacuum and for resonance pressure and it is not related to the regime of development of the discharge.
