New Light Choice for Virtual Skin Biopsy: Multi-Photon Microscopy Driven by Fiber-Based Sources
Imaging & microscopy -, - ()  GO
Harmonic generation microscopy (HGM) is one of the most important techniques for optical virtual skin biopsy. The occurrence of optical harmonics mainly relies on the interaction between ultrafast laser pulses and the skin tissue. [...]

Compact THz Accelerators: From Fiction to Reality
43rd International Conference on Infrared, Millimeter, and Terahertz Waves, IRMMW-THz 2018, NagoyaNagoya, Japan, 9 Sep 2018 - 14 Sep 20182018-09-092018-09-14 IEEE 1-3 () [10.1109/IRMMW-THz.2018.8510463]  GO
The use of THz radiation for electron acceleration and manipulation of electron bunches has progressed over the last decade to a level where practical implementations of THz-powered photoguns, LINACs and a wide range of beam manipulators have become possible. Here, we present a segmented terahertz electron accelerator and manipulator (STEAM) capable of performing multiple high-field operations on the 6D -phase-space of ultrashort electron bunches. [...]
