A Nd:LYSO crystal has been grown by the Czochralski technique. The cell parameters were analyzed with X-ray diffraction (XRD). The Judd-Ofelt intense parameters Omega(2,4,6) were obtained to be 2.65, 5.75, and 7.37x10(-20) cm(2), respectively. The absorption and emission cross sections and the branching ratios were calculated. The large absorption cross section (6.14x10(-20) cm(2)) and broad absorption band (5 nm) around 811 nm indicate that this crystal can be pumped efficiently by laser diodes. The broad emission band from the F-4(3/2) multiplet shows that the crystal is a promising medium for ultrashort pulse lasers. Pumped by a laser diode, the maximum 814 mW continuous-wave laser output has been obtained with a slope efficiency of 28.9%. All the results show that this crystal is a promising laser material.
