The Ultrafast Laser Complex (ULC) consists of two femtosecond laser laboratories (MCMR 132 and 136) and one photophysics laboratory (MCMR 128). The ULC includes numerous commercial and custom-built steady-state and time-resolved optical characterization equipment, including one-of-a-kind femtosecond coherence, two-dimensional electronic, and Stark (electro) absorption spectrometers. Materials dynamics on time scales ranging from 5 fs to 1 s can be measured with light sources whose spectra, dependent on the measurement method, span ~300 to 1,600 nm. The ULC was established by Dr. Ryan Pensack, Dr. Daniel Turner, and Dr. Paul Davis; Dr. Pensack and Dr. Turner currently direct research in the ULC; the ULC is maintained by the ultrafast spectroscopy group and equipment in the photophysics laboratory is frequently used by other teams in the Quantum DNA Research Group.
