Continuous-wave Nd:YVO4 self-raman lasers based on the 379cm-1 and 893cm-1 shifts

This poster reports several Continuous-Wave (CW), self-Raman Nd:YVO4 lasers using the primary and secondary Raman transitions of YVO4 (893cm-1 and 379cm-1 ). Laser outputs were obtained at λ=1109nm, 1158nm and 1231nm with maximum output power of 1W, 700mW and 540mW respectively. The respective absorbed pump power to Raman output power conversion efficiencies were measured at 8.4%, 5.4% and 5.4%. The resulting extended wavelength coverage will be used in conjunction with second harmonic generation and produce lines in the green-lime-yellow region for biophotonics applications where new wavelengths are required to match a growing range of chromophores
