PURPOSE:To optimize the output and the efficiency of a laser by obtaining a laser oscillation relative to neutral atoms and ion spectral beam in a laser medium in the same direction as the propagating direction in the medium of an electron beam and in normal or reverse direction to the direction of the propagating direction of the electron beam. CONSTITUTION:An electron beam 17 generated by electron beam generating means 16 mounted out of a discharge tube 2 is passed through an incident window 18 to be incident to be propagated in the medium 1. Thus, the medium 1 is ionized and excited progressively, and special energy levels of the atoms and the ions of the medium 1 are inverted to be distributed. Then, the light of a spectral beam corresponding to the transfer between the energy levels is reflected on an output mirror 14 at the outside of the tube 2 through a Brewster window 13 to output a laser light 15 in the same direction as the propagating direction in the medium 1 of the beam 17 outside an output mirror 14 and in the same or reverse direction to the direction of the propagation. |
