Summary
We report the design criteria and performance characteristics of a hollow-cathode tube developed especially for high-resolution Doppler-free laser spectroscopy. It is simple to construct and is easily demountable. Narrow homogeneous line widths of refractory and highly reactive-element transitions have been observed by applying intermodulated detection scheme.
Riassunto
Si riportano i criteri costruttivi e le prestazioni di un tubo di scarica a catodo cavo da utilizzarsi in spettroscopia laser ad alta risoluzione. L'apparato è di semplice costruzione e rapidamente adattabile alle diverse esigenze. Sono quindi illustrate misure di spettroscopia optogalvanica senza effetto Doppler e si ottengono righe in larghezza omogenea per elementi anche refrattari ed altamente reattivi.
Резюме
Приводятся конструкционные критерии и характеристики полой катодной трубки, разработанной специально для лазерной спектроскопии высокого разрешения. Аппарат прост по конструкции и легко демонтируется. Иллюстрируются измерения оптогальванической спектроскопиии без эффекта Доплера. Получаются узкие однородные ширины линий для огнеупорных и высокореактивных элементов.
