Doppler-Free Saturated Absorption Laser Spectroscopy
The fundamentals of Doppler-free saturated absorption spectroscopy were explored for a rubidium sample. Two probe laser beams from a 780-nm diode laser were directed through the Rb cell, and one of them was crossed by a pump beam in the opposite direction. Because of the changes in the ground-state population caused by the pump beam, subtraction of the intensity signals from the two probe beams...
متن کاملA Numerical and Analytical Solution for the Free Vibration of Laminated Composites Using Different Plate Theories
An analytical and numerical solution for the free vibration of laminated polymeric composite plates with different layups is studied in this paper. The governing equations of the laminated composite plates are derived from the classical laminated plate theory (CLPT) and the first-order shear deformation plate theory (FSDT). General layups are evaluated by the assumption of cross-ply and angle-p...
متن کاملAnalytical Solution for Free Vibration of a Variable Cross-Section Nonlocal Nanobeam
In this article, small scale effects on free vibration analysis of non-uniform nanobeams is discussed. Small scale effects are modelled after Eringen’s nonlocal elasticity theory while the non-uniformity is presented by exponentially varying width among the beams length with constant thickness. Analytical solution is achieved for free vibration with different boundary conditions. It is shown th...
متن کاملCoherent laser spectroscopy of transient molecules and free radicals
Recent years have witnessed great advances in the study of molecular spectroscopy and dynamics using coherent laser spectroscopy.
