He-Ne (λ = 1.15 μ) laser with two orthogonally polarized modes

摘要

In view of its potential for the intracavity laser refractometry, He-Ne laser with two orthogonally polarized modes at wavelength of 1.15μ was studied. The amplitude and frequency characteristics of this laser were investigated theoretically and experimentally. It has been shown that stable two-mode lasing may be implemented for any split between modes upon applying the transverse magnetic field.
