| 摘 要： | Ho^3＋ ： GdVO4 is a new laser material suitable for high-power laser systems. In this paper we measure the absorption spectra of Ho^3＋ in the sample Ho^3＋： GdVO4. The intensity parameters are calculated by using the Judd-Ofelt theory. Some predicted spectroscopic parameters, such as the spontaneous radiative transition rate, branching ratio and integrated emission cross section are dealt with. And we also compare the optical parameters with those of other materials. From these results, it is found that there are many transitions which have large oscillator strengths and large integrated emission cross sections. Especially the transitions such as ^5 F4 → ^5 I 8, ^5 S2→^5 I8, ^5 F5 → ^5 I8 and ^5 I7 →^ 5 I8 are useful in solid-state lasers and other fields. Finally, we discuss the splitting of the energy levels of Ho^3＋ in the crystal GdVO4 based on the group theory.

| Abstract: | Ho$^{3 + }$,:,GdVO$_{4}$ is a new laser material suitable forhigh-power laser systems. In this paper we measure the absorptionspectra of Ho$^{3 + }$ in the sample Ho$^{3 + }$: GdVO$_{4}$. Theintensity parameters are calculated by using the Judd---Ofelttheory. Some predicted spectroscopic parameters, such as thespontaneous radiative transition rate, branching ratio andintegrated emission cross section are dealt with. And we alsocompare the optical parameters with those of other materials. Fromthese results, it is found that there are many transitions whichhave large oscillator strengths and large integrated emission crosssections. Especially the transitions such as $^{5}$F$_{4} to^{5}$I$_{8}$, $^{ 5}$S$_{2} to ^{5}$I$_{8}$, $^{ 5}$F$_{5} to^{5}$I$_{8}$ and $^{5}$I$_{7} to ^{5}$I$_{8}$ are useful insolid-state lasers and other fields. Finally, we discuss thesplitting of the energy levels of Ho$^{3 + }$ in the crystalGdVO$_{4}$ based on the group theory. |
