摘要
In this Letter, we demonstrate the anisotropy of laser emission in disordered Nd：ScYSiO5 （Nd：SYSO） crystals cut along the optical indicatrix axes. High-powered lasers with different oscillation wavelengths and polariza- tions are realized by using different oriented crystals as gain media. For Y-cut crystals, the dual-wavelength laser vibration direction is found to be along the X axis and a maximum output power of 9.43 W is obtained, giving an optical-to-optical conversion efficiency of 48.8% and a slope efficiency of 51.3%. For X- and Z-cut crystals, 1075 and 1078 nm lasers operating orthogonally polarize oscillate with total output powers of 7.07 and 8.43 W, respectively. The experimental results reveal that the intrinsic anisotropy for the monoclinic disordered laser crystals could make laser design flexible and controllable.
