Abstract
Almost double (a factor of about 1.75) increase is obtained in the power of the radiation with a wavelength of 633nm using combined pumping of the LG-38 He−Ne laser by the direct and inductive (3 MHz) currents. It is found that the maximum power is attained at a lower (by about 30%) direct current.
