Damage behaviors in Nd:YVO4 by multi-energy proton implantation

Enhanced Raman Spectra in Femtosecond Laser Inscribed Yb:YVO4 Channel Waveguides

“…Raman peak positions were listed in Table 2, where none extra peak and peak shift existence in waveguide areas and Yb:YVO 4 substrate comparing with the results in Refs. [16,17,23]. The experiment modes vary with different wavelengths.…”

“…The photographs of waveguides structures with the widths of 6, 12, 18, and 24 µm were captured using a metallographic microscope with reflected polarized light. Model profiles at TE Observed modes (cm −1 )@633 nm Experimental modes (cm −1 )@473 nm [16] Experimental modes (cm −1 )@514.5 nm [17] Experimental modes (cm −1 )@514.5 nm [8] Assigned Raman modes [8,16,17] and TM polarization were captured using the endface coupling setup at the wavelength of 633 nm. The results imply that the width of two lines fabricated using the laser writing influences the light guiding.…”

“…So, channel waveguide structure with double lines in Nd:YVO 4 crystal was studied by femtosecond laser inscription [15]. As an excellent optical materials, waveguides in Nd:YVO 4 crystal have been also fabricated using ion irradiation with proton [16], N [17], Si [18], He [19], O [20] ions and swift Kr ions [21].…”

Nanopowders Y1−yNdyV1−xCrxO4 with y=0 and 1; x=0, 0.1, 0.2 and 0.5 synthesized by a sol–gel process. Relationship between morphological characteristics and optical properties

“…Neodymium doped yttrium orthovanadate YVO 4 :Nd is widely used as an outstanding laser material because of its excellent thermal, optical and mechanical properties as well as its high luminescence efficiency [12]. During the past decade, YVO 4 :Nd has been extensively grown as single crystals by different methods, such as flux or floating zone [13], while less commonly as nanoparticles [9] or nanopowders [14].…”
