description: This work is devoted to the study of anti-Stokes luminescence in BeAl2O4,
Y3Al5O12, YAlO3 crystals, their thermal balance and the possibility of optical cooling
under laser excitation in the long-wave wing of the absorption spectrum. Tasks to be
solved during the research:
1. Obtaining Stokes and anti-Stokes luminescence spectra of samples under laser excitation.
2. Measurement of the thermal response of samples under laser excitation
in the absence of thermal contact.
3. Analysis of the received data.
Standard optical spectroscopy methods were used to obtain the Stokes and
anti-Stokes luminescence spectra of samples. The thermal response and time dependences of the sample temperature under the action of exciting laser radiation in
thermal isolation were obtained by non-contact method using infrared thermometry.
As a result of the experiments, net optical cooling was not achieved, but a
decrease in the heating of the samples was registered.
The results of this work can be used in further research on the search for new
materials for optical cooling.
