Mild ablation of biological objects under the submillimeter radiation of the free electron laser

First line of FEL with smooth tuning of irradiation wavelength 100-200 microns and 400 W power is commissioned in Siberian Center for Photochemical Research. Irradiation was used for mild ablation of DNA, enzymes, and proteins. Transfer from surface occurs without molecular destruction. Particle size was determined using aerosol diffusion spectrometer.
