Performances of Cr:LiSrAlF(6) and Cr:LiSrGaF(6) for continuous-wave diode-pumped Q-switched operation.
We have developed a Cr:LiSrGaF(6) laser that produces, in Q -switched operation, four times as much energy (12 microJ at 10 kHz) as a Cr:LiSrAlF(6) laser under the same conditions of pumping (four red diodes emitting 400 mW). By using a theoretical model for small-signal gain calculations, we show that these better performances are mainly attributable to the fact that thermal quenching of fluorescence is lower in Cr:LiSrGaF(6) than in Cr:LiSrAlF(6).
