High-precision FoM measurement setup for Ti:Sapphire crystals
Vojtech Miller, Karel Zidek
The figure of merit (FoM) of Ti:Sapphire (Ti:Sa) crystals is a generally used means to evaluate the quality of the crystals. Despite the importance of Ti:Sa, the question of FoM me…
Differential Coded Aperture Single-Snapshot Spectral Imaging
Jiri Hlubucek, Jakub Lukes, Jan Vaclavik +1
We propose a novel concept of differential coded aperture snapshot spectral imaging (D-CASSI) technique exploiting the benefits of using {-1,+1} random mask, which is demonstrated…
Nanosecond compressive fluorescence lifetime microscopy imaging via the RATS method with a direct reconstruction of lifetime maps
Jiri Junek, Karel Zidek
RAndom Temporal Signals (RATS) method has proven to be a useful and versatile method for measuring photoluminescence (PL) dynamics and fluorescence lifetime imaging (FLIM). Here, w…
Beating signals in CdSe quantum dots measured by low-temperature 2D spectroscopy
Zhengjun Wang, Albin Hedse, Edoardo Amarotti +5
Advances in ultrafast spectroscopy can provide access to dynamics involving nontrivial quantum correlations and their evolutions. In coherent 2D spectroscopy, the oscillatory time…
Noise effect on 2D photoluminescence decay analysis using the RATS method in single-pixel camera configuration
Jiri Junek, Karel Zidek
Using a random temporal signal for sample excitation (RATS method) is a new, efficient approach to measuring photoluminescence (PL) dynamics. The method can be used in single-point…
Fluorescence lifetime imaging via spatio-temporal speckle patterns in single-pixel camera configuration
Jiri Junek, Karel Zidek
Photoluminesce (PL) spectroscopy offers excellent methods for mapping the PL decay on the nanosecond time scale. However, capturing maps of emission dynamics on the microsecond tim…
Collection of micromirror-modulated light in the single-pixel broadband hyperspectral microscope
Lukas Klein, Karel Zidek
Digital micromirror device (DMD) serves in a significant part of computational optical setups as a means of encoding an image by the desired pattern. The most prominent is its usag…
Random temporal laser speckles for robust measurement of sub-microsecond photoluminescence decay
Jiri Junek, Lukas Ondic, Karel Zidek
Time-resolved photoluminescence (PL) is commonly used to track dynamics in a broad range of materials. Thus, the search for simplification of the acquisition of PL kinetics attract…
Compressive imaging of transient absorption dynamics on the femtosecond timescale
Ondřej Denk, Kaibo Zheng, Donatas Zigmantas +1
Femtosecond spectroscopy is an important tool for tracking rapid photoinduced processes in a variety of materials. To spatially map the processes in a sample would substantially ex…
Multiple exciton generation in nano-crystals revisited: Consistent calculation of the yield based on pump-probe spectroscopy
Khadga J. Karki, Fei Ma, Kaibo Zheng +7
Multiple exciton generation (MEG) is a process in which more than one exciton is generated upon the absorption of a high energy photon, typically higher than two times the band gap…
