Novel small-angle collective Thomson scattering system.
A Thomson scattering opticals system is described with the following characteristics: (1) it allows scattering angles down to 1 mrad before collection optics interfere with beam dumping; (2) it gives excellent k resolution for angles of > or approximately 1.5 mrad; (3) it collects light from a scattering volume which can be variably positioned without optical realignment; and (4) it is compact in size. The design, test data, and an application to ruby-laser scattering from 100-microm wavelength plasma waves are presented.
