Abstract
We propose an accurate measurement of the evolution of the emission cross section of versus temperature around . This was done by using two complementary methods involving spectrum acquisition and laser oscillator small signal gain measurement. We observed a 44% decrease of the peak emission cross section for a temperature increase but also a shift of the peak emission cross section wavelength at a rate of . The influence of the crystal temperature on the performance of a laser oscillator in continuous wave was also investigated.
