Abstract

We demonstrate application of the thermal reflectance measurement in a balanced detector arrangement to resolve laser induced temperature shifts in ytterbium-doped yttrium-lithium-fluoride (Yb:YLF) during optical refrigeration experiments. Definite signature of cooling versus heating allows for rapid screening of the performance of the laser cooling material.
