Influence of summation of excitations on the efficiency of lasing of sensitized media

Synthesis and properties of solution-processed Eu3+:BaY2F8

“…The first room temperature operation UC laser was reported in BaYb 2 F 8 :Er 3+ [6]. Since efficient NIR laser diodes became available as pumping sources, it is possible to apply the UC process as a possible operating scheme for compact and efficient visible lasers.…”
