Type of experiment: Inelastic Brillouin light scattering microscopy on solid and soft matter
Description: Confocal microscopy with
diffraction-limited resolution of 360 nm. The scattered light from the sample
surface is analyzed by a high-contrast six-pass Tandem Fabry–Perot
interferometer TFP-1 (JRS Scientific
Instruments). The BLS intensity proportional to the square of the amplitude of
plane dynamics(Phonons, magnons) at the
corresponding frequency(300 MHz-2 THz).
Beam parameters: Spectral Linewidth: <10 MHz, 532nm 200 mW.
Auxiliary equipment: Radio frequency components, Spectrum analyzer 40 GHz, EOM 40 GHz, Time tagger 30 ps.
