The contribution is oriented towards measuring in the nanoscale through local probe microscopy techniques, primarily the AFM microscopy. The need to make the AFM microscope a nanometrology tool not only the positioning of the tip has to be based on precise measurements but the traceability of the measuring technique has to be ensured up to the primary etalon. This leads to the engagement of laser interferometric measuring methods. We present a design of a single-frequency stabilized laser which serves as a laser source for multiaxis position control of a nanopositioning stage. We have decided for a frequency-doubled Nd:YAG laser with thermal frequency control locked to a Doppler-broadened absorption line in iodine. The laser stabilization technique is described together with comparison of frequency stability.
