在单晶中，多声子受激喇曼散射相互作用以及不同形式的级联和交叉级联的非线性χ(3)↔χ(3)过程都是由皮秒激光脉冲引发的。通过对YAlO_3晶体受激拉曼散射性质的研究，极大地拓展了它的科学应用潜力。特别是，研究揭示了八种χ(3)-主动振动模式的表现。指定了相应的斯托克斯线和反斯托克斯线，并估算了与最强声子模有关的稳态拉曼增益系数。此外，还简要介绍了Ln3+离子的受激发射通道以及Y_2O_3-Al_2O_3二元系统晶体的一些χ(3)非线性激光性质。
In single crystals of orthorhombic YAlO3, widely known as a host‐matrix for Ln3+‐lasant ions, many‐phonon stimulated Raman scattering interactions as well as different manifestations of cascaded and cross‐cascaded nonlinear χ(3)↔χ(3) processes are initiated by picosecond laser pulses. The scientific and applicative potential of YAlO3 crystals is considerably expanded by the demonstration of its SRS properties. In particular, the studies revealed the manifestation of eight χ(3)‐active vibrational modes. The corresponding Stokes and anti‐Stokes lines have been assigned and the steady‐state Raman gain coefficients related to the strongest phonon mode have been estimated. In addition, a short review presents the stimulated emission channels of its Ln3+‐ions together with some χ(3)‐nonlinear laser properties of crystals belonging to the binary Y2O3‐Al2O3 system.
