The effect of a longitudinal magnetic field on the output power of a 6328 Å at helium-neon laser was investigated experimentally under the gas pressure in the range of 0.5 to 1.5 Torr. Laser output power began to change at about 15 Gauss and rapidly increased as the magnetic field increased. Laser output power reached the peak value when the magnetic field was in the range of 150 to 200 Gauss. But laser action stopped when the magnetic field was between 300 and 600 Gauss. To investigate these causes, we observed the variation of electron temperature and electron density by the double probe method. The spectra of side and end light were measured on its laser tube. The cause of the change of electron temperature and electron density on laser action was also considered.
