“…Researchers have examined other condensed matter systems beyond RE-doped materials, with an emphasis on semiconductors [17,[43][44][45][46]. Semiconductor coolers provide more efficient pump light absorption, the potential of much lower temperatures, and the opportunity for direct integration into electronic and photonic devices.…”

We present an overview of solid-state optical refrigeration also known as laser cooling in solids by fluorescence upconversion. The idea of cooling a solid-state optical material by simply shining a laser beam onto it may sound counter intuitive but is rapidly becoming a promising technology for future cryocoolers. We chart the evolution of this science in rare-earth doped solids and semiconductors.Measured cooling efficiency as a function of the pump laser wavelength for a 1.2% Tm +3 doped BaY2F8 crystal at room temperature. The solid line is calculated using the absorption spectrum [30].

Anti-Stokes luminescence in heavily doped semiconductors as a mechanism of laser cooling

The anti-Stokes luminescence is a mechanism of the optical refrigeration in semiconductor light sources. The heavily doped semiconductors are considered as a material for the laser cooling. The limitation of this mechanism appears to be connected with a transition from the non-degenerate to degenerate occupation. This transition occurs at higher pumping rate (along with the transition to the optical gain and lasing) and at lower temperature. Thus, the limit for the laser cooling can be indicated. The minimal obtainable temperature is about 60–120 K depending on the doping level. The laser cooling of a semiconductor is impeded by the difficulty of extracting the spontaneous emission from a radiating body that is characterized by large angle of the total internal reflection.

“…Indeed, now more than ever the field of laser cooling is a topic of intense on-going theoretical and experimental investigations. The previous theories attempting to model the laser cooling phenomenon are rate-type theories [11,12]. The problem with these theories is that they neglect the change of the carrier distribution when the temperature is changed.…”
