Small-scale, all-solid-state, frequency-doubled intracavity Raman laser producing 5 m W yellow-orange output at 598 nm

The varied applications of a small-scale, diode-pumped, Q-switched Nd:YVO₄ laser with intercavity Raman laser producing 5 mW yellow-orange output at 598 nm were discussed. The Raman and second-harmonic frequency conversion had the highest average powers and optical conversion efficiencies. Efficient Raman frequency conversion required high power density of the fundamental laser drive. The results show flexibility in the wavelengths that were generated using the two step intercavity Raman and second harmonic generation process.
