Single-Shot Imaging of Bose-Einstein Condensed Photon Gas Using the iXon Ultra 897 EMCCD Camera
4 Mar 2016This application note describes an experiment where Bose-Einstein condensed photon gas is thermalized to room temperature, and imaged using an EMCCD camera. Bose-Einstein condensation, the macroscopic ground state population of a system of integer spin particles below a critical temperature, has in the last 20 years been observed for cold atomic gases and solid state quasiparticles as exciton polaritons. The most widely known example of a photonic gas, blackbody radiation, however exhibits no Bose-Einstein condensation. The results of this experiment hold prospects for the exploration of novel states of light, e.g. also in periodic potentials, and for light sources in new wavelength regimes.

iXon Ultra 897 EMCCD Camera
Oxford Instruments AndorFacilitated by a fundamental redesign, the NEW iXon Ultra platform takes the popular back-illuminated 512 x 512 frame transfer sensor and overclocks readout to 17 MHz, pushing speed performance to an outstanding 56 fps (full frame), whilst maintaining quantitative stability throughout. The status of ‘Ultimate Sensitivity’ is also preserved in this model, offering thermoelectric cooling down to -100°C and industry-lowest clock induced charge noise. Additional unique features of the iXon Ultra include USB connectivity and direct raw data access for on the fly processing. EMCCD and conventional CCD readout modes provide heightened application flexibility, with a new ‘low and slow’ noise performance in CCD mode.
