Abstract:

Work is presented on the operation, beam characteristics, and biomedical-materials research and sapphire fiber development with the Stanford Mark III free Electron Laser. The MK III FEL has been operated in the wavelength range of 2 micrometers to 4 micrometers at up to 4 mJ per pulse 1-2 microsec. Irradiances as high as 800 GWcm2 have been obtained with pulse durations as low as 350 femto seconds. Preliminary studies with sapphire fibers are underway in the 2-4 micrometer range. Preliminary studies with biological samples including gallstones, kidney stones and egg shells and in vivo soft tissue samples including albino mouse ear skin and vasculature and with semiconductor materials have been carried over a biologically important water absorption peak approximately 2.94 micrometers has been demonstrated.
