Abstract
The discharge current influence on the homogeneous broadening of the spectral lines in the gas-discharge media by direct collisions of the excited atoms with free electrons and also through collision broadening changing because of the gas heating by discharge current is considered. It was established that homogeneous broadening and hence the frequency shift of the spectral line depend essentially on the thermal condition of the laser work. The theoretical calculations are confirmed by the experimental measurements of the dependence of the homogeneous broadening of spectral line 3s2 - 2p4 neona in the He-Ne laser on the discharge current magnitude. For the homogeneous broadening determination by the experimentally measured Lamb dip characteristics a new computation method was developed, which can be used both in single-mode and two axial modes conditions of laser generation. It has been shown that on its basis and using known dependencies of the collision broadening of the spectral lines on the pressure, there can be realized an express-control of the main sources of the generation frequency unreproducibility in the sealed off discharge tubes, such as gas pressure and relative excitation of the laser system.
