Laser Cooling of a Semiconductor Load to 165 K

Not Accessible

Your library or personal account may give you access

Abstract

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