- We discuss the coherent population trapping (CPT) effect induced in a three-level -type system by a train of short pulses. Specifically, we consider a modified 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".
