Laboratory for IR-VIS ultrafast spectroscopy (CLARK)

This ultrafast spectroscopy system is based on two synchronized non-collinear optical parametric amplifiers (NOPAs). Each NOPA can be independently configured to generate broadband visible laser pulses with sub-10-fs duration, tunable 15-fs pulses in the visible (from 500nm to 720nm), tunable near-infrared (from 900nm to 1500nm) pulses with 15-30 fs duration or 15-20-fs blue pulses (430-480 nm wavelength range). This equipment allows one to perform pump-probe experiments on a broad spectral range, equal to almost two octaves, and with extreme temporal resolution.
