Concentration dependence of energy transfer upconversion in Nd:YAG
نویسندگان
چکیده
The concentration dependence of energy transfer upconversion in Nd:YAG is investigated via the z-scan technique. The ETU coefficient is determined to increase from 35×10 -18 cm 3 /s to 90×10 -18 cm 3 /s when the concentration increases from 0.3 at.% to 1.1 at.%. OCIS codes: (190.7220) Upconversion; (140.3530) Lasers, neodymium; (300.6460) Spectroscopy, saturation.

Upconversion luminescence of an insulator involving a band to band multiphoton excitation process.
A multiphoton process to the conduction band of the insulator Er2O3 is reported, which occurs in vacuum under near infrared excitation. The enormous upconversion intensity is two orders of magnitude greater than that in air, and also the intensity ratio for green and red emission bands is inverted. The mechanism is probed by experiments of laser power dependence, cathodoluminescence, photocondu...
متن کاملConcentration quenching in fine-grained ceramic Nd:YAG.
We have studied the concentration dependent fluorescence decay kinetics of ceramic Nd:YAG, to resolve inconsistencies in the previous literature. Our data indicate that earlier reports of single exponential lifetimes even at Nd concentrations of a few percent were due to the effects of long-pulse excitation. Under short-pulse excitation the fluorescence decay is nonexponential for concentration...
متن کاملSub-quadratic Dependence of Visible Upconversion on Infra-red Direct Luminescence Decay Owing to Static Energy-transfer Upconversion
We investigate the influence of active-ion distributions on energy-transfer upconversion (ETU) in a static upconversion regime in which energy migration is inactive and the active local environment is important for the dynamics of ETU. Neodymium is used as the probe ion. In oxide and fluoride host materials, Nd3+ possesses only one metastable excited state (4F3/2) from which strong ETU occurs. ...
متن کاملRepetition-rate dependence of thermal loading in diode-end-pumped Q-switched lasers: influence of energy-transfer upconversion
The fractional thermal loading in diode-endpumped Q-switched lasers was estimated from the theory of cavity stability. The experimental results show that the thermal loading depends on the pulse-repetition rate. This dependence is attributed to the effect of energy-transfer upconversion (ETU). A theoretical model including the ETU effect was developed to analyze the fractional thermal loading i...
متن کاملDependence of Upconversion on Direct Luminescence Decay in Energy-transfer Upconversion
For several decades, energy-transfer upconversion (ETU) in rare-earth-ion doped systems [1,2] has attracted much attention, firstly, because of the fundamental interest in the physical nature of this process and, secondly, because of very practical considerations, namely the demonstration of near-infrared pumped visible light sources and, in reverse, the detrimental influence of ETU on the effi...
