Femtosecond double pulse microcavity dispersion imaging optical setup
The setup is designed to perform optical analysis of polariton microcavities at room temperature under two pulses excitation in a pump-probe regime.
Excitation is provided by a Coherent Libra amplified Ti:Sapphire laser and a Coherent OPerA SOLO optical parametrical. The setup is tuned to provide synchronized single pulses at 800nm or 400nm and 530-540nm with a pulsewidth ~200fs. The excitation repetition rate varies in the range 10-500Hz. The analyzed polariton microcavity is held in a free-standing optical setup which directs emission towards a real-space and energy dispersion imaging system (Princeton Instruments Acton SpectraPro SP-2750 spectrometer and ProEM HS CCD camera supported by LightField® software).
Excitation Tunability: wavelength range 400, 800 and 530-540nm
Optical pulse energy: Up to 1 mJ per pulse at 800nm
Optical pulse FWHM: 200fs
Temperature Tunability: Room temperature
Measurement Flexibility: Transmission and reflection measurement schemes, real and Fourier space imaging, spectroscopy
