Paper Abstract

Analytical closed-form expressions for the pumping efficiency, passive loss, and the effective emission cross section are derived for threshold lasing in homogeneously broadened four-level laser media. These expressions are discussed with respect to existing discrepancies in the literature. The analytical results are applied to threshold-lasing measurements in flashlamp-pumped Cr:Nd:GSAG and Cr:Nd:YSGG as compared to Cr:Nd:GSGG.
