AI Article Synopsis
- Researchers achieved nonlinear pulse compression at high powers using a unique fiber amplification system.
- They generated 700 fs pulses with significant energy and average power by utilizing a large pitch photonic crystal fiber with a 1 MHz repetition rate.
- This process included spectral broadening in a xenon-filled hollow-core fiber, resulting in ultra-short 81 fs pulses with 93 μJ energy, a first for transmitting over 100 W through such a fiber.
Article Abstract
We report on nonlinear pulse compression at very high average power. A high-power fiber chirped pulse amplification system based on a novel large pitch photonic crystal fiber delivers 700 fs pulses with 200 μJ pulse energy at a 1 MHz repetition rate, resulting in 200 W of average power. Subsequent spectral broadening in a xenon-filled hollow-core fiber and pulse compression with chirped mirrors is employed for pulse shortening and peak power enhancement. For the first time, to our knowledge, more than 100 W of average power are transmitted through a noble-gas-filled hollow fiber. After pulse compression of 81 fs, 93 μJ pulses are obtained at a 1 MHz repetition rate.

Acute Arterial Ischemia Secondary to Intrapelvic Acetabular Migration: A Multidisciplinary Approach.

This case report evaluates current diagnostic and treatment approaches for intrapelvic acetabular migration, focusing on the rare but serious complication of acute limb ischemia following hip arthroplasty. A 67-year-old female with a history of total hip arthroplasty 10 years ago presented with acute limb ischemia after experiencing a traumatic event 72 hours prior, which had caused displacement of her hip prosthesis. Notably, she had a history of a traumatic event two years earlier for which she had been advised to undergo surgical correction, which she had refused.

Studying the properties and phase diagram of iron at high-pressure and high-temperature conditions has relevant implications for Earth's inner structure and dynamics and the temperature of the inner core boundary (ICB) at 330 GPa. Also, a hexagonal-closed packed to body-centered cubic (bcc) phase transition has been predicted by many theoretical works but observed only in a few experiments. The recent coupling of high-power laser with advanced x-ray sources from synchrotrons allows for novel approaches to address these issues.

Sport-related concussions are a common type of brain injury, and the best treatment is prevention. Recently, external jugular vein compression collars have been worn by National Football League players, but the current evidence is limited. To the best of the authors' knowledge, this is the first comprehensive, up-to-date systematic review addressing the use of jugular vein compression collars for decreasing concussion incidence in high-impact sports and activities.

This study explores the mechanical properties of geopolymer mortars incorporating ceramic and glass powders sourced from industrial waste. A Box-Behnken design was employed to assess the effects of ceramic waste powder (CWP) content, alkaline activator ratio, solution-to-binder (S: B) ratio, and oven curing duration on the mortar's performance. Compressive strengths were measured at 3 and 28 days, and regression models were developed to predict these outcomes.
