Diode pumped continuous-wave intracavity Raman conversion in a composite Nd:KGW/KGW crystal has been investigated. The use of a Nd:KGW/KGW crystal instead of the ordinary Nd:KGW crystal has made it possible to considerably decrease intracavity losses. A Raman threshold corresponding to a diode laser power of 230 mW and a quantum efficiency of conversion of diode laser radiation to the Stokes radiation of 22% have been obtained.
