BRIEF COMMUNICATIONS: Thermal conductivity of a Y1.5Er1.5Al5O12 crystal in the temperature range 5-300 K
The temperature dependence of the thermal conductivity of a laser element made of a Y1.5Er1.5Al5O12 crystal was determined in the temperature range 5?300 K. Values of the thermal conductivity at room and liquid nitrogen temperatures, important in practical applications, were found.
