摘要：
An investigation of Tm-Ho energy transfer in Tm(5at.%), Ho(0.4at.%):KYW single crystal by two independent techiques was performed. Based on fluorescence dynamics measurements, energy transfer parameters P-71 and P-28 for direct (Tm -> Ho) and back (Ho -> Tm) transfers, respectively, as well as equilibrium constant Theta were evaluated. The obtained results were supported by calculation of microscopic interaction parameters according to the Forster-Dexter theory for a dipoledipole interaction. Diode-pumped continuous-wave operation of Tm, Ho:KYW microchip laser was demonstrated, for the first time to our knowledge. Maximum output power of 77 mW at 2070 nm was achieved at the fundamental TEM00 mode. (C) 2016 Optical Society of America
