Make/Model: Coherent Libra, Ultrafast Helios/EOS Location: MolES G21 Femtosecond laser with transient absorption and streak camera photoluminescence detection. The excitation source for both Transient absorption and photoluminescence experiments is the Coherent Libra amplified Ti:Sapphire laser, which generates 50 fs pulses of 800 nm light at 1 kHz. Using one of two Optical Parametric Amplifiers (OPAs), this light can be converted to any wavelength between 350 nm and 2400 nm, while retaining a pulse-width of less than 100 fs. Transient absorption experiments are performed using the Helios and EOS units from Ultrafast Systems, while time-resolved photoluminescence experiments are performed using a streak camera from Hamamatsu. Key Capabilities - 800 nm, 50 fs, 1 kHz fundamental laser source - TA detection from ~300 - 2400 nm with time scale from ~100 fs - ms - PL detection from 300 - 950 nm - OPA range from 350 - 2600 nm Compatible Samples - Compatible with both thin film and liquid phase samples - Sample must allow transmission of probe light
