摘要: Abstract We report on the fabrication of planar waveguide in x-cut Nd:YVO4 laser crystal formed by 1.98 GeV with fluence 2 × 1010 ions/cm2 swift Kr8+ ion irradiation. The investigation absorption bands and photoluminescence spectra demonstrates that transmission properties bulk Nd3+ luminescence features have been preserved after In Raman spectra, peak positions widths had no obvious change irradiated cross section along an accurate size measurement region buried beneath surface were observed a microscope transmitted polarized light. also measured near-field intensity distributions light end-face coupling method.
