Thermal diffusivity of Au nanofluid was measured by using a dual beam mode-mismatched thermal lens method. The samples were prepared in various sizes by utilizing the gamma radiation method. In the dual beam mode-mismatched thermal lens, a diode laser (532 nm) was used as an excitation beam and a He-Ne laser with the beam output at 632.8 nm was used as a probe beam. Thermal diffusivity of gold...
متن کاملAbsorption coefficient of nearly transparent liquids measured using thermal lens spectrometry
We use an optimized pump-probe mode-mismatched thermal lens scheme to determine the optical absorption coefficient and thermal diffusivity of ethanol, benzene, acetone, methanol, toluene and chloroform. In this scheme the excitation beam is focused in the presence of a collimated probe beam. The agreement between experimentally obtained results and values reported in the literature is good.
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. ...

Objective(s): A novel IQ-SPECTTM method has become widely used in clinical studies. The present study compares the quality of myocardial perfusion images (MPI) acquired using the IQ-SPECTTM (IQ-mode),conventional (180° apart: C-mode) and L-mode (90° apart: L-mode) systems. We assessed spatial resolution, image reproducibility and quantifiability using various physical phantoms. Materials and Me...
متن کاملDesign , Modeling , Optimization , and Experimental Tests of a Particle Beam Width Probe for the Aerodyne Aerosol
Aerodynamic lens inlets have revolutionized aerosol mass spectrometry by allowing the introduction of a very narrow particle beam into a vacuum chamber for subsequent analysis. The real-time measurement of particle beam width after an aerodynamic lens is of interest for two reasons: (1) it allows a correction to be made to the measured particle concentration if the beam is so broad, due to poor...
