摘要：
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 lambda = 1067 and 1181 nm.
