Raman System with double side laser heating for diamond anvil cells (DAC)

Contact: Alex Goncharov
Location: R-140

Double-sided Yb fiber laser heating system interfaced with Raman systems for high P-T Raman spectroscopy (Fig. 1). This system has two excitation wavelengths 457 and 488 nm, and it is capable to measure in situ Raman spectra at high temperatures in a laser heated DAC up to 2200 K. A ps acoustic setup combined with this system to study elasticity at high pressures is under development.
