thermal expansion/ He-Ne laser wavelength-shifting interferometrythermal expansionlaser cavitywarm-up timeThe use of wavelength-shifting interferometry with a He–Ne laser source is presented. The approach is based on the thermal expansion of the laser cavity during the warm-up time, in conjunction ...
A simple approximation of the wavelength of single frequency He-Ne laser as a function of temperature, pressure and relative humidity is presented. This approximation is suitable for the simple application in the portable laser interferometer. Comparison with the Owens and Edln formulae is also ...
