Quantum Cascade Lasers For Spectroscopic Applications. Feasibility And Asset For Muonic-Hydrogen Experiment (original) (raw)

Characterization of a laser source capable of achieving a high pulsed power density with tunability around 7µm. This source is dedicated to experiment of muonic atoms spectroscopy. Conditions for experiment: pulsed laser source (high power density, tunable wavelength ~6.8 µm and linewidth <0.07 nm). Quantum Cascade Lasers (QCLs) are appropriate laser source for the muonichydrogen experiment: tunable emission wavelength, good precision and high optical power . To shows that QCLs are suitable candidates for the muonic-hydrogen experiment, We performed the tunability of QCLs as function of the temperature and the applied voltage, by measuring at different temperatures and voltages, to look for the moving of the emission wavelength. We give a summary of the measurements performed on QCLs.
