Avoiding the opposite beams interaction in the He−Ne linear laser at 632.8 nm

Summary In the paper the role of the opposite beams in laser generations is discussed on the basis of experimental investigations performed on the He−Ne long linear laser. It is stated that standing waves do not interact with atoms in one-photon transitions. Laser oscillations always avoid generating standing waves inside the laser medium. The best way to avoid such standing waves is laser generation in the form of one short pulse travelling to and fro inside the resonator—the self-locking generation. Also discussed is the laser generation of two or more pulses inside the resonator. The work was supported by CPBR 8.14.
