Coherent population trapping with a train of pulses via a continuum and its application to the suppression of excited-state absorption Academic Article uri icon

abstract

  • We discuss the coherent population trapping (CPT) effect induced in a three-level Λ-type system by a train of short pulses. Specifically, we consider a modified Λ system with the upper level replaced by a continuum of states. We show that CPT with a train of pulses can be applied to the suppression of excited-state absorption of pump radiation in crystalline laser materials. The utility of the technique for pumping a promising yellow-orange solid-state medium Ti:YAlO3 and overcoming excited-state pump absorption is analyzed. © 2007 MAIK "Nauka/Interperiodica".
