Lasing in a solid-state inhomogeneously diode end-pumped Nd : KGW/Cr⁴⁺ : YAG laser is obtained at wavelengths of 1067 and 1181 nm (Stokes shift 901 cm⁻¹) under conditions of frequency degeneracy of cavity modes. In this case, the radiation has a characteristic ring spatial structure, which testifies to transverse mode locking of the fundamental and Stokes components. The possibility of controlling the Raman conversion efficiency by changing the position of an undoped KGW crystal additionally installed in the cavity is demonstrated. It is shown that the transverse mode locking is accompanied by the total longitudinal mode locking at λ = 1067 and 1181 nm.

在腔模频率简并条件下，在固态非均匀二极管端泵浦 Nd : KGW/Cr ⁴⁺ : YAG 激光中获得波长为 1067 和 1181 nm（斯托克斯位移 901 cm ^-1）。在这种情况下，辐射具有特征性的环形空间结构，这证明了基本分量和斯托克斯分量的横向锁模。证明了通过改变额外安装在腔中的未掺杂 KGW 晶体的位置来控制拉曼转换效率的可能性。结果表明，横向锁模伴随着λ = 1067 和 1181 nm 处的总纵向锁模。
