Stable Deuterium-Tritium plasmas with improved confinement in the presence of energetic-ion instabilities.

Providing stable and clean energy sources is a necessity for the increasing demands of humanity. Energy produced by Deuterium (D) and Tritium (T) fusion reactions, in particular in tokamaks, is a promising path towards that goal. However, there is little experience with plasmas formed by D-T mixtures, since most of the experiments are currently performed in pure D.

Preloaded DMEK with endo-in technique: Standardizing and minimizing the learning curve over 5 years using 599 corneal tissues.

Purpose: To report the outcomes of standardizing pre-loaded DMEK with endothelium-inwards and its associated learning curve.

Methods: Between 2017 and 2021, a total of 599 tissues were stripped using 'trephine and strip' method and loaded by folding the tissue as a taco-fold with endothelium-inwards. The folded tissues were pulled inside the funnel of a 2.

Eye Bank Management of Irregular Descemet Stripping Automated Endothelial Keratoplasty Lenticules.

Purpose: To report the management of precut Descemet stripping automated endothelial keratoplasty (DSAEK) lenticules unsuitable for transplantation because of irregular anterior profile after microkeratome cutting.

Methods: After preparation for DSAEK, 20 tissues were considered unsuitable for transplantation because of nonhomogeneous posterior stromal thickness. To convert them into suitable tissues for surgery, manual stromal delamination was performed by removing the excess stromal layers after the indications obtained through optical coherence tomography.

DFG-based mid-IR tunable source with 0.5 mJ energy and a 30 pm linewidth.

We report on a laser system based on difference frequency generation (DFG) to produce tunable, narrow-linewidth (<30), and comparatively high-energy mid-IR radiation in the 6.8 µm region. The system exploits a lithium thioindate () nonlinear crystal and nanosecond pulses generated by single-frequency Nd:YAG and Cr:forsterite lasers at 1064 and 1262 nm, respectively.

24 mJ Cr:forsterite four-stage master-oscillator power-amplifier laser system for high resolution mid-infrared spectroscopy.

We present the design of a Cr:forsterite based single-frequency master-oscillator power-amplifier laser system delivering much higher output energy compared to previous literature reports. The system has four amplifying stages with two-pass configuration each, thus enabling the generation of 24 mJ output energy in the spectral region around 1262 nm. It is demonstrated that the presented Cr:forsterite amplifier preserves high spectral and pulse quality, allowing a straightforward energy scaling.
