报道了在天然透锂长石LiAlSi_4 O_（10）单斜晶体中发现χ（3）非线性激光的受激拉曼散射（SRS）。所有记录的斯托克斯和反斯托克斯激光边带在皮秒激光泵浦下的可见光被识别，并归因于两个发生的SRS促进声子模式，ω SRS 1 <$490 cm−1和ω SRS 2 <$357 cm−1。简要回顾了已知的SRS活性晶体矿物及其观测到的χ（2）和χ（3）非线性相互作用的表现。
The discovery of χ(3)–nonlinear lasing by stimulated Raman scattering (SRS) in natural monoclinic crystal of petalite, LiAlSi4O10, is reported. All recorded Stokes and anti-Stokes lasing sidebands under picosecond laser pumping in the visible are identified and attributed to the two occurring SRS-promoting phonon modes with ωSRS1 ≈ 490 cm−1 and ωSRS2 ≈ 357 cm−1. A short review of known SRS-active crystalline minerals and observed manifestations of their χ(2)– and χ(3)–nonlinear interactions is given as well.
