A report is given of a systematic experimental investigation of the possibility of constructing an electron-beam-excited laser in which the upper active level is filled as a result of recombination of a supercooled stationary plasma and the lower level is depopulated by ionization of an impurity gas (L. I. Gudzenko, M. V. Nezlin, and S. I. Yakovlenko, Sov. Phys. Tech. Phys. 18, 1218 (1974)). The presentation of the experimental data is preceded by an analysis of a laser system differing from other treatment of the same subject (L. I. Gudzenko, M. V. Nezlin, and S. I. Yakovlenko, ibid.; Yu. I. Syst'ko and S. I. Yakovlenko, Sov. J. Quantum Electron. 5, 364 (1975); L. I. Gudzenko, L. A. Shelepin, and S. I. Yakovlenko, Sov. Phys. Usp. 17, 848 (1975)) by complete and correct allowance for the principal elementary proceses and by solution of the self-consistent problem. Systematic experiments give a clear negative result. The fundamental correctness of this result is demonstrated. A comparison is made of the present results with the calculations carried out by other authors. The reported experiments have been made possible by the generation (S. V. Antipov, M. V. Nezlin, E. N. Snezhkin, and A. S. Trubnikov, Sov. Phys. JETP 38, 931 (1974); E. N. Snezhkin and M. V. Nezlin, Sov. Phys. JETP 46, No. 3 (1977)) of a quasistationary supercooled ''beam'' plasma with an electron temperature T/sub e/< or approx. =0.2 eV, helium plasma density N/sub e/ >10/sup 14/ cm/sup -3/ and helium--hydrogen mixture concentration N/sub 0/=10/sup 18/--10/sup 19/ cm/sup -3/.
