Project of the Slovak Grant Agency VEGA 2/7081/27

Project duration: 01/2007 - 12/2009

Head of the project: RNDr. Ing. Ján Bartl CSc.

Aim of the project

The aim of this scientific project is solving, theoretical as much as experimental, problems following from the use of diode laser for metrological purposes by optical frequency stabilization by saturated absorption method in ¹²⁷I₂ iodine isotope vapors. Project sets itself the task of achieving the technical equipment allowing beat frequency comparison of extended cavity diode laser (ECDL) with national length etalon.

This project is a follow-up to research of the optical frequency spectra of iodine stabilized HeNe lasers completed at the Slovak Metrological Institute and diode lasers realized at the Institute of Measurement Science, SAS. This research is based on realization of 633 nm diode laser system with extended cavity resonator and its optical frequency spectrum (474 THz) is stabilized on hyperfine components of iodine molecule quantum transition.

Project also put the accent on active integration of young researchers - internal PhD. students into project research under supervising of their supervisor.
