Abstract :
The two-wavelength generation in He-Ne laser resonator has been used for the interferometric measurements of displacements and strains. The oscillations on 0,63 and 3,39 microns are simultaneously realized and investigated. The precise multi-channel temperature meter with resolution of 0,001 K in the 273-378 K range was applied for temperature monitoring of the laser. The interferometric schemes are based on a three-mirror laser resonator using a principle of an optical feedback. The interferometer length was ranged from a few meters up to 300 meters in our experiments. Fabrication of a dispersion interferometer - refractometer, which corrects of a refractive index along the extended measuring baseline, is possible with this technique application.
