摘要：	The funding provided by DURIP program was used to acquire an ultrafast laser spectroscopy system with extensive material characterization capabilities. The new system is based on Coherent Astrella Ti:Sapphire regenerative amplifier coupled to LightConversion TOPAS?Prime optical parametric amplifier and LightConversion NIRUVVIS optical mixer unit. The system is capable of producing ~120 fs laser pulses with wavelength continuously tunable in the range 220-2600 nm. Also, DURIP funding was used to acquire instrumentation necessary for the laser system operation (detectors, oscilloscope, computer interface cards, and safety equipment). The laser system was integrated into UCSB Optical Characterization Facility to extend its capabilities and meet the needs of campus researchers. It has been used successfully in ultrafast pump-probe experiments, time-resolved studies of phosphorescent materials, laser-induced activation of cancer treatment drugs prototypes. It has been instrumental in research projects funded by DoD (ARO and ONR), NSF, and collaborative interuniversity efforts.
