Two-Color NIR Transient Absorption and Emission Spectrometer is built off of an amplified Newport Spectra-Physics amplified femtosecond laser system. It is equipped with two OPAs, one operational in the visible and NIR, and the other in the NIR to IR regions. Requests for semiconductor quantum dots (QD) and nanotube photophysics require probe wavelengths beyond 1400 nm. The system is also equipped with a Hamamatsu C5680 streak camera system with 2-ps temporal resolution, and a closed-cycle liquid He cryostat.
