Cavitation appears in many semi-crystalline polymers when they are subjected to uniaxial stretching above their glass transition temperatures. Generally, the formation of voids isinfluenced by the morphology of semi-crystalline polymers, including their lamellae thickness, lamellae orientation, as well as the arrangement of the amorphous phase [...]

A cryogenic Yb:YAG composite-thin-disk amplifier produced one-joule diffraction limited pulses at 200 Hz and 50% optical-to-optical efficiency. As of this writing 20 hours in operation have been compiled recording $< 0.5%$-power and $< 30 µrad$ pointing stability..

We demonstrate a fiber-based ultrafast platform generating energetic femtosecond pulses at 1250 nm and 775 nm simultaneously, which enables label-free second-harmonic generation, third-harmonic generation, and two-photon excitation fluorescence imaging in human skin..

Millijoule-scale multicycle terahertz (THz) sources have recently gained interest for applications where high-peak-fields and narrow bandwidths can produce unique results, such as linear and nonlinear spectroscopy [1], control of matter [2], and compact electron acceleration [3]. Difference frequency generation (DFG) using periodically-poled lithium niobate (PPLN) is a very promising method for producing such pulses, due to the high nonlinear coefficient of lithium niobate and the tunability of the periodic poling.

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. [...]
