Speaker:   Boris Knyazev (Budker Inst. of Nucl. Physics, Novosibirsk State U)

Title:     Operation and Applications of a 400 W Average Power Terahertz Free Electron Laser based upon an Energy Recovery Linac

Abstract: Budker Institute of Nuclear Physics is a research institute of Siberian Branch of Russian Academy of Science in Novosibirsk, Russia. Main fields of activity in the institute are electron accelerators, high-energy physics, plasma physics and accelerator technology. Full scale Novosibirsk free electron laser (NFEL) based on accellerator-recuperator is to generate tens kW average power radiation in the spectral range from 3 to 300 micrometers and will be constructed within next three years. At present, recently commisioned first stage of the laser generates continuous train of 50-ps pulses of 120? 170 mum tunable monochromatic coherent radiation with average power up to 400 W (there is no source in the world with such characteristics in this spectral range). Principle of operation of free electron laser (FEL) and specific features of Novosibirsk FEL will be described. Common survey of rapidly developing terahertz science and technology will be done. Experiments on continuous optical discharge, laser ablation, desorption of DNA without denaturation, imaging and holography in the terahertz spectral range carried out on NFEL will be described in brief.


Stimulants available 15 minutes before the talk.
