Heat, Fluorescence, and Stimulated-Emission Power Densities and Fractions in Nd:YAG
نویسنده
چکیده
We present a comprehensive theory describing the CW balance of heat and fluorescence powers in Nd:YAG and discuss the individual and total heat, fluorescence, and stimulatedemission fractions of the absorbed power, with or without stimulated emission, and as a function of the Nd doping density. values are presented for both CW and pulsed diode pumping. It is shown that heating due to multiphonon emission and concentration quenching alone cannot account for recent CW measurements of the heat fraction, but that upconversion appears to be a negligible effect.

Glucose 6-phosphate dehydrogenase (G6PD) from Streptomyces aureofaciens was purified and denatured in 6 M urea. Denaturation led to complete dissociation of the enzyme into its inactive monomers, 98% loss of the enzyme activity, about 30% decrease in the protein fluorescence and a 10 nm red shift in the emission maximum. Dilution of urea-denatured enzyme resulted in regaining of the enzyme acti...
متن کاملThermal lens spectrometry in Nd:YAG without and with laser action at 1064 and 1340 nm
The pump-probe TL spectrometry was used, for the first time to our knowledge, to study heat generation, fluorescence quantum efficiency, and thermal properties of Nd:YAG under laser action at 1064 and 1340 nm, and without laser operation. The results showed that the thermal loading was strongly dependent on laser emission wavelength, being >2 times when operating at 1340nm compared to 1064 nm. ...
