"We present the design of several types of extended-cavity lasers (ECL) based on the Littman.sup.1./sup. configuration and an arrangement for an external stabilizating scheme employing Doppler-free saturation spectroscopy in the molecular iodine. The ECLs followed the requirements of metrological applications where the stress has been put to mechanical stability, thermal control, narrow linewidth and a mode-hop free tuning range. We developed the thechnique of antireflection coatings of the laser diodes front facets which proved to be a crucial step towards the internal cavity suppression and propper operation to the ECL. To control the laser optical frequency an electronics consisting of a precise thermal control and a current source with a protective circuitry was designed."@en . "\u010C\u00EDp, Ond\u0159ej" .
