Abstract

We have developed a non-contact spectroscopic technique to measure the temperature change of Thulium-doped glasses and crystals with high precision. The approach makes use of temperature-dependent broadening of various peaks in the luminescence spectra. A weak, cw probe laser excites the sample in vacuum. The luminescence spectrum is collected by a fiber and routed to a high-resolution spectrometer. We have demonstrated temperature resolution of 62 mK in Tm:BaY₂F₈.
