First set-up of the laser interferometer with tunable semiconductor laser is presented. To reduce the influence of the index of refraction of air, the design of optical set-up of the experimental interferometer is realized using fiber optics. VCSEL diodes (Vertical Surface Emitting Laser) and DFB laser diodes (Distributed FeedBack) were used in our setup of the laser interferometer. Comparison of the frequency stability and the wavelength tuneability of these laser diodes are presented. In our first set-up of the laser interferometer was used the method of the frequency stabilization on optical resonator to stabilize of frequency of laser diodes and measurement of the tuneability of the wavelength. Measurement of absolute values can be providing by this laser interferometer.
