2D Chalcogenide Thin Films for Super-Resolved Laser Structuring [PDF]

EPJ Web of Conferences, 2023
The saturable absorption behaviour associated with chalcogenide thin films has been investigated and optimized using Z-Scan Technique. Huge saturable absorption responses (of the order of 10^-7 m/W) were observed for the Bismuth Selenide thin films ...

Miniaturized saturated absorption spectrometer [PDF]

Review of Scientific Instruments, 2020
We describe a saturated absorption spectrometer that is robust and compact and requires minimum alignment, which is made possible by using a diffuse probe beam generated by a retro-reflecting film. This concept was studied and implemented in a miniaturized home-built setup that provides the same performance as an optimized table-top setup.

Super-resolution computational saturated absorption microscopy

Journal of the Optical Society of America A, 2023
Imaging beyond the diffraction limit barrier has attracted wide attention due to the ability to resolve previously hidden image features. Of the various super-resolution microscopy techniques available, a particularly simple method called saturated excitation microscopy (SAX) requires only simple modification of a laser scanning microscope: The ...
