Enhanced Raman Spectra in Femtosecond Laser Inscribed Yb:YVO4 Channel Waveguides
The femtosecond laser writing with double-line technique was employed to fabricate buried channel waveguides with different widths in Yb:YVO4 crystal. Model profiles of the waveguides were captured using the endface coupling setup at the wavelength of 633 nm under TE and TM polarization. Furthermore...
