Abstract

A record low temperature in optical refrigeration is demonstrated by cooling Yb:YLF crystal to 128K ± 5K (∼−150 C) at λ=1020 nm corresponding to its E4-E5 Stark manifold resonance. The estimated cooling power is 165 mW.

We report new milestones in the solid-state laser cooling by demonstrating cooling Yb:YLF below 123K (NIST-defined cryogenic) at the E4-E5 Stark resonance. Furthermore, we show impedance-matched cavity-enhanced cooling geometry truly mimics a laser running in reverse.

Local laser cooling of Yb:YLF to 110 K

Minimum achievable temperature of ~110 K is measured in a 5% doped Yb:YLF crystal at λ = 1020 nm, corresponding to E4-E5 resonance of Stark manifold. This measurement is in excellent agreement with the laser cooling model and was made possible by employing a novel and sensitive implementation of differential luminescence thermometry using balanced photo-detectors.

We demonstrate cooling of a 2 micron thick GaAs/InGaP double-heterostructure to 165 K from ambient using an all-solid-state optical refrigerator. Cooler is comprised of Yb3+-doped YLF crystal, pumped by 9 Watt near E4-E5 Stark manifold transition.

Demonstration of an Optical Cryocooler

We present the first observation of cryogenic operation in an all-solid-state refrigerator. A temperature drop of ~150 K is demonstrated in a 0.2 cm3 rare-earth doped fluoride crystal (Yb:YLF) using anti-Stokes fluorescence, at a record cooling power of 110 mW. Lowest electronic transition within Yb3+ Stark manifold along with cavity enhanced absorption and thermal load management were key in achieving this operation. We show that temperatures down to 100 K are achievable in this arrangement given sufficient absorbed laser power at 1020 nm.
