The accelerated electrons are above the ground energy, and, thus, they represent a population inversion. In the wiggler, the beam’s transverse undulations yield synchrotron radiation, the analogue of a conventional laser material’s fluorescence. The light initially emits spontaneously, but in a typ...
The etching properties of a SF6-based 150W-biased plasma discharge, using as additive this new HBPO gas, shows that negligible damage can be achieved at −50 °C, with acceptable etch rates. The evolution of the damage depth as a function of time was studied without bias and indicates ...
In this paper, a laser etching technology with advantages of simple process, low cost, and high machining accuracy is used to directly etch the free-standing MXene-molybdenum disulfide (MoS2) film for MSC. As adding MoS2 in MXene effectively improves the electrochemical performance, such as a ...
HOBOKEN, N.J., April 13, 2011 — A high-speed communications technology not limited by a physical conductor such as fiber optics has been developed using laser light to transmit data through readily available open space. This optical free space communication could lead to faster Internet for ...
In summary, EUV light was demonstrated to be free light-shape focused by single self-evolutionary PSs with a capillary-discharge 46.9-nm laser in terms of vortex focus shaping, array focusing, and structured-light shaping. The strong medium absorption led to difficult focusing and imaging in the...
(Fig.4c, d). The measurement does not use vibration isolation, acoustic shielding, or temperature control of the resonator reference cavity. Hence low-frequency noise is dominated by environmental effects. The free-running laser 1/π-integral linewidth75is 21.3 kHz, and the β-separation ...
Fabrication of the nanofluidic chips was carried out in cleanroom facilities of Federal Standard 209 E Class 10–100, using electron-beam lithography (JBX-9300FS/JEOL Ltd), Ion-beam etching (Ionfab 300 Plus/Oxford Plasma Technology), photolithography (MA6/Suss MicroTec), reactive-ion etching (...
In this study, we have observed the wavefront of single shots at a hard X-ray free-electron laser. In particular, we have measured the distortions introduced by the offset mirror system, which we show to be slightly horizontally collimating and stable from shot-to-shot. Further, we have ...
