Glossary of terms
Side lines (SL)
Unwanted emission besides the nominal wavelength value, often disturbing in spectroscopy and interferometry. Can be suppressed by special mirror technology.
Polarization switching (PS)
Sudden changes of the polarization of different modes espacially in short tubes. Particularly disturbing when HeNe laser tubes are used in frequency stabilized operation. Can be eliminated by special selection process.
Two longitudinal modes (LM)
Tube supports exact two orthogonally polarized longitudinal modes. Required for special methods of frequency stabilization.
Magnetic field stability (MF)
The above characteristics are also guaranteed in the presence of a strong magnetic field up to 3 G
Split frequencies (SF)
Frequency split of He-Ne laser modes in the presence of a strong magnetic field (> 200 G). Can be used for obtaining extremely high frequency stability. LASOS® has been successful in developing tubes with specific split frequencies for defined magnetic fields.
