Femtosecond-laser-written, stress-induced Nd:YVO4 waveguides preserving fluorescence and Raman gain

We report the formation of optical waveguides in the self-Raman Nd:YVO4 laser crystal by femtosecond laser inscription. The confocal fluorescence and Raman images have revealed that the waveguide is constituted by a locally compressed area in which the original fluorescence and Raman gains of the Nd...

Sumario:We report the formation of optical waveguides in the self-Raman Nd:YVO4 laser crystal by femtosecond laser inscription. The confocal fluorescence and Raman images have revealed that the waveguide is constituted by a locally compressed area in which the original fluorescence and Raman gains of the Nd:YVO4 system are preserved. Thus the obtained structures emerge as promising candidates for highly efficient self- Raman integrated laser sources.
