Generation of sum frequency mixing radiation at cw intracavity Raman conversion

Recent obtaining continuous-wave (cw) Raman conversion in solid-state laser system [1] opens perspectives for creation of new cw laser sources at new wavelengths by means of further nonlinear conversion. Thus, intracavity frequency-doubled cw crystalline Raman laser was reported lately [2]. This report presents first data on investigation of intracavity sum-frequency generation in diode pumped solid state laser on Nd:YVO 4 with self frequency Raman conversion.
