Abstract :
The elements of heterodyne laser spectrometer based on the optical comb and frequency stabilized referent lasers is presented. The optical comb is generated by radiation of Ti:Sa femtosecond laser spectrally enlarged by a photonic crystal fibre. Iodine stabilized He-Ne laser is used as reference and external cavity diode laser locked onto the iodine hyperfine transition is used as frequency marker. The application of spectrometer for precise measurement of molecular iodine lines wavelengths in red spectral region is considered.
