Varshni maintained that the emission lines observed in QSOs can be satisfactorily explained as being due to laser action in certain atomic species in the expanding envelope of a star and having no appreciable redshift. In order to test this hypothesis we have examined the conditions conducive to laser action in the stellar atmosphere and compared all the emission lines of 633 QSOs discovered till August 1976 (as listed by Burbidge et al.) with the laser transitions found in the laboratory till April 1976 (as listed by Willett and Beck et al,). It was found that 88% of the QSO lines agreed to within 10 ,~ with the laser lines and 94% agreed to within 20 .&. The main reason Greenstein and Schmidt failed to fit the spectral lines of 3C 48 and 3C 273 with known emission lines is that laser transitions in hydrogen do not occur in stellar atmospheres. The spectra are explained on the basis of the new theory and the broadening of lines explained.
