Paper Abstract

Basic concepts involved in inversionless laser schemes are reviewed. We focus on the V scheme recently proposed by the Stanford group, which uses AC Stark coupling to develop overlapping spectral lines that show an interference minimum in absorption and a maximum in emission at line center. The He-like C 1s(superscript 2/ - 1s2p transition is examined as a possible candidate for developing an absorption minimum; Doppler broadening effects are found to be severe. The situation is improved with the choice of heavier ions and stronger resonance lines in closed shell sequences. New short wavelength laser schemes in these systems are proposed.
