Title: Optical Characterization of Nd3+ and Er3+ Doped-Lead-Indium Phosphate Glasses

Abstract

In this work, Judd-Ofelt analysis is applied to rare-earth-doped lead-indium-phosphate glasses (RE-PbInPO{sub 4}, where RE = Er{sup 3+} and Nd{sup 3+}) in order to evaluate their potential as both glass laser systems and amplifier materials. The phenomenological Judd-Ofelt parameters {Omega}{sub (2)}, {Omega}{sub (4)}, and {Omega}{sub (6)} are determined for both rare-earth ions together with their quality factors and compared with the equivalent parameters for several other host glasses. The spontaneous emission probabilities and the lifetimes of the Nd{sup 3+} {sup 4}F{sub 3/2} laser transitions are determined and analyzed as a function of the optical quality factor. For Nd{sup 3+}-PbInPO{sub 4}, glass fluorescence emission (890, 1058, and 1330 nm) lines are observed. Highly efficient infrared-to-visible frequency up-conversion at 530, 550, and 670 nm as well as an intense infrared fluorescence emission ({approx}1540 nm) is observed in Er{sup 3+}-doped PbIn(PO{sub 4}) glasses pumped using 800 nm radiation excitation.

  • The experimental determination of thermal and optical properties, such as the fluorescence quantum efficiency ( ) and temperature coefficient of the optical path length change, (ds/dT), has been a challenging task. In this work, mode-mismatched thermal lens and spectroscopic measurements were performed using Er3+-, Nd3+-, and Pr3+-doped lead-indium-phosphate glasses to obtain the thermal diffusivity and conductivity, ds/dT, the thermal loading (nonradiative quantum efficiency), and . The experimental difficulties associated with obtaining for systems with several emitting levels, such as Er3+-doped materials, were overcome. A discussion of the implications of the small values obtained for Er3+- and Pr3+-doped glass, is presented.

  • The spectroscopic characteristics of Er3+-doped lead phosphate glasses have been investigated, and Judd-Ofelt analysis was used to evaluate the effect of increasing the Er3+ content on the glass matrices. The intensity-dependent Judd=-Ofelt parameters: (4) and (6) remained constant while (2) decreased. Photoluminescence analysis revealed a low up-conversion efficiency through the weak green (530 and 550 nm) and red (660 nm) signals that were present under excitation at 800 nm. The concentration quenching effect on the lifetime of the Er3+: 4I13/2 4I15/2 (1530 nm) transition is also evaluated as a result of the addition of Er3+ to the lead phosphate glassmore » composition. The observed relatively large reduction in the lifetime reflects the significant effects of non-radiative processes in this system. The potential use of these glasses as photonic devices is also discussed.« less
  • In this work, we have used the thermal lens technique combined with conventional spectroscopy to characterize the thermo-optical properties of Er3+-doped lead pyrophosphate-based glasses. More precisely, we have investigated and quantified experimentally the fluorescence quantum efficiencies of the Er3+ levels, and we describe the role of concentration quenching effects. The fluorescence quantum efficiency of the 4I13/2 level is very high when compared to other phosphate glasses, while that of the green-coupled levels is very small. Other important photonic materials parameters, such as the thermal diffusivity and temperature coefficient of the optical path length change, were obtained and compared with thosemore » of other glass systems. The cumulative results obtained here for the Er-doped lead pyrophosphate glass show that this material is a good candidate for photonic applications with a characteristic Er3+ infrared emission around 1550 nm.« less
  • The third-order optical susceptibility and dispersion of the linear refractive index of Er3+-doped lead phosphate glass were measured in the wavelength range between 400 and 1940 nm by using the spectrally resolved femtosecond Maker fringes technique. The nonlinear refractive index obtained from the third-order susceptibility was found to be five times higher than that of silica, indicating that Er3+-doped lead phosphate glass is a potential candidate to be used as the base component for the fabrication of photonic devices. For comparison purposes, the Z-scan technique was also employed to obtain the values of the nonlinear refractive index of E-doped leadmore » phosphate glass at several wavelengths, and the values obtained using the two techniques agree to within 15%.« less
