Abstract :
In this work we report on the 2-mum laser emission of LiLuF4 crystals doped with thulium trivalent ions (Tm:LLF) at different doping density up to 16%. We will present our results regarding growth, absorption and emission spectroscopy, Judd-Ofelt analysis and room temperature diode pumping laser experiments as a function of the dopant density. The best result is 56% of slope efficiency, with a maximum output power of 280 mW. The emission wavelength ranges between 1985 and 2038 nm, exploiting the vibronic emission of Tm in LLF.
