Stimulated Raman adiabatic passage for improved performance of a cold-atom electron and ion source
We implement high-efficiency coherent excitation to a Rydberg state using stimulated Raman adiabatic passage in a cold-atom electron and ion source. We achieve an efficiency of 60% averaged over the laser excitation volume with a peak efficiency of 82%, a 1.6 times improvement relative to incoherent pulsed-laser excitation. Using pulsed electric field ionization of the Rydberg atoms we create e...
متن کاملPsfc/ja-02-24 Studies of Stimulated Raman Scattering in Laser Plasma Interactions
Coupled theoretical and computational work is presented aimed at understanding and modeling stimulated Raman backscattering (SRBS) relevant to laser-plasma interactions (LPIs) in large-scale, nearly homogeneous plasmas. With the aid of a new code for simulating and studying the nonlinear coupling in space-time of a large number of modes, and a fluid Vlasov-Maxwell code for studying the evolutio...
متن کاملLabel-Free Biomedical Imaging Using High-Speed Lock-In Pixel Sensor for Stimulated Raman Scattering
Raman imaging eliminates the need for staining procedures, providing label-free imaging to study biological samples. Recent developments in stimulated Raman scattering (SRS) have achieved fast acquisition speed and hyperspectral imaging. However, there has been a problem of lack of detectors suitable for MHz modulation rate parallel detection, detecting multiple small SRS signals while eliminat...
متن کاملEffect of bias voltage on structural and mechanical characteristics of diamond-like carbon thin film applied by ion beam deposition
This study, investigates the effect of bias voltage on structural changes of diamond-like carbon thin film created by ion beam deposition is investigated. For this purpose, the bias voltage in the values of 0 V, -50 V, -100 V and -150 V on the AA5083 aluminum alloy was considered. Raman spectroscopy was used to evaluate structural. Influence of the bias voltage on the thickness and roughness of...
متن کاملScaling of saturated stimulated Raman scattering with temperature and intensity in ignition scale plasmas
Measurements show the scaling of stimulated Raman scattering ~SRS! with laser intensity and plasma electron temperature under the conditions expected in ignition experiments. The scaling of the scattered energy with each parameter follows a power law with a small exponent ~of order 1!. Comparison with simulations suggests SRS is nonlinearly saturated in these cases. Further experiments with hig...
