英文摘要The Yb:YAG is an excellent high-average power and ultra-short pulse laser crystal. Transition intensity parameters A(tp)(t) and Huang-Rhys factors are fitted to its emission spectrum by the full-profile fitting method. Calculated results indicate that the emission spectrum of Yb: YAG at cryogenic temperature consists of three pure electron state transitions and two phonon-assisted transitions, one vibronic transition releases one-phonon of 3 cm(-1), and the other vibronic transition absorbs onephonon of 22 cm(-1). At 300 K, the phonon assisted transition of 3 cm(-1) turns into two-or more-phonon assisted transitions. The procedure absorbing phonon can reduce the thermal load of Yb: YAG and improve the laser efficiency, which may be one of the reasons why Yb: YAG has excellent performance. The emission bands of Yb: YAG are broadened thermally, and the peak values decrease by several times. The emission cross sections of Yb: YAG determined by Fuchtbauer-Ladenburg (F-L) formula are remarkably different from those calculated with A(tp)(t), which indicates that it is necessary for a laser material to determine its transition intensity parameters A(tp)(t) in order to reasonably evaluate the laser performance.
