Comparative studies of high power diode-pumped Yb:CALGO and Yb:KYW lasers

摘要

A direct comparison of continuous-wave diode-pumped Yb:CALGO and Yb:KYW lasers was demonstrated. The laserswere characterized not only in terms of output power but also in terms of thermal lensing. The results showed that in themedium to low power regimes the Yb:KYW laser outperformed the Yb:CALGO laser in terms of optical efficiency,however, in high power regime the latter showed much more favorable thermal behavior than Yb:KYW.
