Abstract

We laser cooled ytterbium doped silica to 255 K. Temperature-dependent spectroscopy measurements reveal cooling to 150 K is possible. We also report the observation of site-selective excitation in Yb, Al co-doped silica.

Temperature-dependent spectroscopy of Yb:YLF and prospects for laser cooling

Ytterbium-doped materials are promising for high power solid-state lasers as well as laser cooling [1] . Cooling of Yb-doped fluoride crystals, particularly LiYF 4 (YLF), has been very successful, achieving cooling of high purity Yb:YLF crystals to below 100 K [2] . Here, we revisit the detailed temperature-dependent spectroscopy of Yb:YLF in order to fully reveal its potential as a laser cooling medium and to address requirements to achieve the liquid nitrogen temperature at 77 K.

An energy transfer accompanied by phonon absorption in ytterbium-doped yttrium aluminum perovskite for optical refrigeration

Yuta Nakayama, Yukihiro Harada, Takashi Kita

Yttrium aluminum perovskite (YAP) is a host material that can provide a strong emission from a rare-earth dopant and it has a lower phonon energy than yttrium aluminum garnet (YAG). Therefore, YAP is a promising material for optical refrigeration and radiation balanced laser. We measured the photoluminescence (PL) spectra of ytterbium (Yb)-doped YAP and compared them with those of Yb-doped YAG. The estimated ideal laser cooling efficiencies of Yb-doped YAP and Yb-doped YAG were comparable at 300 K. Based on the temperature-dependent anti-Stokes PL, we found that the laser cooling power of Yb-doped YAP at 470 K is 14.3 times higher than that at 200 K. This enhancement at higher temperatures is 3.2 times larger than that observed for Yb-doped YAG. We attributed the higher laser cooling power of Yb-doped YAP to a lower multi-phonon relaxation rate (and/or a higher energy transfer rate) and an antenna effect caused by the energy transfer from Yb ions that are located at the Y-site to Yb ions that are surrounded by an inhomogeneous alloy structure. The calculated small signal gain of (Yb:Y)AP is 3.5 times larger than that of (Yb:Y)AG. The larger small signal gain of (Yb:Y)AP arises from its strong absorbance and small Stark splitting width.

We will report the first demonstration of an optically cooled fiber amplifier. The fiber was made of silica, had a core doped with Yb, and was core-pumped to achieve both gain and cooling in the core via anti-Stokes fluorescence. Gains larger than 10 dB were measured while maintaining a negative average temperature change along the fiber.

Features of laser cooling of Yb-doped fluorite nanocrystals using coherent population transfer techniques

Tatiana Vovk, Semyon S. Rudyi, Andrei V. Ivanov +2 more

As of today, one of the milestones in quantum theory testing is obtaining of macroscopic quantum states, for which very low temperatures are necessary. Such low energies can be present during optical and optomechanical cooling of nanostructures. Here we investigate the deep cooling of ytterbium-doped fluorite nanocrystal via coherent population transfer techniques. We consider two main approaches towards coherent transfer, namely, Raman pulses and stimulated Raman adiabatic passage, and search for the most efficient cooling parameters. Optimization of the process of deep nanocrystal cooling opens up possibilities for various applications and technologies.
