- September 2007 -
BioCARS is completing infrastructure changes that aim to expand our time resolution from 5ns to ~100 ps and to enable data collection within a single 100-ps X-ray pulse. These enhancements are a collaboration with Philip Anfinrud (NIH/NIDDK) and are partly supported by funding from NIH/NIDDK.
There were three major activities in this project.
The laser system is a Ti:Sapphire Spitfire Pro 5 from Spectra Physics (780nm, 2ps, 5mJ/pulse, 1kHz).
It is equipped with a TOPAS optical parametric amplifier from Light Conversion.
The output of TOPAS is tunable in a wide wavelength range:
75µJ @ 290-400nm
>300µJ @ 475-600nm
>250µJ @ 600-800nm
