Determination of Yb:CALGO Crystal Properties: Absorption Coefficient vs. Doping Concentration
1.Introduction Yb:CALGO crystals are ideal gain media for high-power, ultrafast laser systems due to their excellent thermal and spectral properties. Their broadband emission properties enable them to support the generation of ultrashort pulses, while the high thermal conductivity helps to maintain a stable laser output at high power pumping. The doping concentration of Yb:CALGO crystals is limited by the difference in concentration between the raw material ratio and the final product, resulting in the limitations of traditional methods of evaluating the concentration of the crystals to accurately reflect the performance of the crystals in real-world applications.
