Photothermal cantilever deflection spectroscopy
Microcantilever sensors offer high sensitivity in the detection of adsorbed molecules based either on resonance frequency shift or changes in cantilever deflection, as both of these signals can be detected with very high resolution. Despite the high sensitivity offered by this platform, cantilevers suffer from poor selectivity due to the lack of sufficiently selective interfacial layers which c...
متن کاملPhotothermal deflection spectroscopy and detection.
The theory for a sensitive spectroscopy based on the photothermal deflection of a laser beam is developed. We consider cw and pulsed cases of both transverse and collinear photothermal deflection spectroscopy for solids, liquids, gases, and thin films. The predictions of the theory are experimentally verified, its implications for imaging and microscopy are given, and the sources of noise are a...
متن کاملDYE JET VELOCITY DISTRIBUTION MEASUREMENTS USING PHOTOTHERMAL DEFLECTION SPECTROSCOPY
We demonstrate that photothermal deflection spectroscopy can be used to measure velocity distributions in dye jets. Such measurements are useful in determining the quality of flow in dye jets, The quality of jets is very important for a stable and naanow linewidth operation of dye lasers

متن کاملContinuous-wave photothermal deflection spectroscopy with fundamental and harmonic responses.
A diffraction theory of continuous-wave photothermal deflection (PD) spectroscopy with fundamental and harmonic responses is presented. The displacement of the probe beam centroid is found to be a rigorous measurement of PD effect, which leads to a set of analytical solutions to the fundamental and the second-order harmonics. Harmonics are caused by the diffraction of the probe beam in the mira...
