Role of Yb2+ in Yb:CaF2 for Lasing and Optical Refrigeration

Hiroki Tanaka, Stefan Püschel, Christian Kränkel

Abstract

We investigated the influence of Yb2+ on the spectroscopic properties of Yb:CaF2. A strong nonradiative decay of Yb3+ was observed in an Yb2+-rich crystal, so Yb2+ is highly detrimental for lasing and optical refrigeration.

Cooperative Optical Transitions in CaF2:Yb3+

H.Y. Zhang, Richard T. Brundage, William M. Yen

It has been shown that Yb3+ ions in crystalline hosts can exhibit optical transitions involving pairs of ions, either two Yb3+ ions1 or Yb3+ paired with another rare earth, such as Gd3+, 2 or upconversion processes involving a number of Yb3+ ions.3 We have studied such transitions in CaF2:Yb using tunable laser spectroscopy.

Spectroscopic indications of the possible optical cooling effect in fluoride crystals activated by Yb3+ and Tm3+ ions

Larisa A. Nurtdinova, Vadim Vladimirovich Semashko, А. К. Наумов +2 more

The results of spectral kinetic studies of several fluoride crystals activated by Yb 3+ and Tm 3+ ions are presented, and their possible application as cooling elements of optical refrigerators is discussed. Optimum excitation conditions for the laser cooling effect in these crystals are found. The cooling efficiency is established to depend on the degree of order in the active medium.

Laser Cooling of an Yb3+-doped Cubic KY3F10 Single Crystal

Stefan Püschel, Christian Kränkel, Hiroki Tanaka

We present temperature-dependent spectroscopy of cubic Yb:KY3F10 and report on its first laser cooling. In comparison with Yb:YLF, Yb:KY3F10 has an intrinsically higher cooling potential at low temperatures so suited for optical refrigerators.

Loss processes on crystal cooling efficiency

Francesco Caminati, Giovanni Cittadino, Eugenio Damiano +2 more

In the perspective of building a solid state cryocooler based on optical refrigeration, it is strategic to develop high purity crystals and to have a full understanding of the mechanisms that can reduce cooling efficiency. In this paper we highlight two loss mechanisms that can hinder the optical refrigeration performance of a Yb:YLF monocrystal: the presence of impurities and fluorescence reabsorption. We show how the presence of impurities can be inferred by measuring the mean lifetime of the Yb optical transition. We measure how a few ppms of other rare earth ions can be detrimental for optical refrigeration by exciting a cooling Yb:YLF sample with two laser sources. We also report the first practical demonstration of the negative effect of fluorescence reabsorption on the cooling performance.

Comparison of Yb3+: YAP with Yb3+: YAG cooling crystals

Chaoyu Wang, Jianping Yin

Abstract YAlO 3 (YAP) shows lower phonon energy than Y 3 Al 5 O 12 (YAG), which implies a lower temperature can be obtained in Yb 3+ -doped YAP according to the single-frequency phonon model. Here, a 2% Yb 3+ : YAP crystal was refrigerated by anti-Stokes fluorescence and compared to YAG crystal with the same doping concentration in experiments. Yb 3+ exhibited a broad spectral cooling range in YAP from 1020nm to 1070nm, which was broader than in YAG from 1020 nm to 1055 nm. A minimum achievable temperature (MAT) dropped to ~ 249.7 K at 1040 nm for Yb 3+ : YAP, which was lower than that of ~ 259.3 K obtained in 2% Yb 3+ : YAG. Further analysis predicted that the cooling limit of two crystals can reach ~167 K for Yb 3+ : YAP and ~171 K for Yb 3+ : YAG from room temperature. This work exhibited the excellent cooling properties of Yb 3+ : YAP compared with Yb 3+ : YAG in experiment and provided a unique perspective for the practical application of high-power Radiation balance lasers (RBLs).
