Abstract

We have shown to our knowledge for the first time the absorption spectrum of Kr between 1500 and 1580 nm via the opto-galvanic effect and we measured the stability of a laser locked to the absorption line of Kr 1s²-2p⁸ at 1547.825 nm. The noise of the Galvatron signal as a function of the current through the bulb was carried out. Additionally it was shown to our knowledge for the first time that is it possible to lock more than one laser simultaneously at different wavelengths to one Galvatron tube
