Measurement of Background Energy Content of a Linear cw Colliding PulseMode-Locked Dye Laser [PDF]

, 1991
The background energy content of a linear cw CPM rhodamine 6G-DODCI femtosecond dye laser is determined by time- resolved measurement of the Rayleigh scattered signal in a colloidal silicon dioxid suspension with an ungated inverse time- correlated ...

Compact-eight channel photon counting module with monolithic array detector

, 2007
We present a multichannel photon counting module that exploits a monolithic array of single-photon avalanche diodes (SPADs). The detector array consists of eight 50μm diameter SPADs featuring low dark counting rate and high photon detection efficiency ...

Compressive Reconstruction Based on Sparse Autoencoder Network Prior for Single-Pixel Imaging

Photonics, 2023
The combination of single-pixel imaging and single photon-counting technology enables ultra-high-sensitivity photon-counting imaging. In order to shorten the reconstruction time of single-photon counting, the algorithm of compressed sensing is used to ...

Raman‐based label‐free microscopic analysis of the pancreas in living zebrafish larvae

FEBS Open Bio, EarlyView.
Forward stimulated Raman scattering (F‐SRS) and epi coherent anti‐Stokes Raman scattering (E‐CARS) allow label‐free discrimination of distinct subcellular structures in the pancreas of living zebrafish larvae. Given the straightforward applicability, we anticipate broad implementation of Raman microscopy in other organs and across various biomedical ...

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

FEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐
