The Impact of Postoperative Intravenous Iron Therapy on Clinical Outcomes in Surgical Patients with Iron-Deficiency Anemia: A Comparative Analysis by Frailty Status in the Setting of Elective Cardiac Surgery

Medicina
Background and Objectives: This study aimed to comparatively investigate the impact of postoperative intravenous iron therapy (IVIT) as an add-on to preoperative IVIT on clinical outcomes in frail versus non-frail patients with iron-deficiency anemia ...

Enhancing laser beam performance by interfering intense laser beamlets

Nature Communications, 2019
Enhanced coupling of laser energy to the target particles is a fundamental issue in laser-plasma interactions. Here the authors demonstrate increased photon absorption leading into higher laser to electron and proton energy transfer through the ...

Longitudinal Laser Shaping in Laser Wakefield Accelerators [PDF]

, 2000
We study the energetics of wake excitation during the laser-plasma interaction in application to laser wakefield accelerators. We find that both the wake amplitude and the accelerating efficiency (transformer ratio) can be maximized by properly shaping ...

Mode-selective toroidal mirrors for unstable resonator planar waveguide and thin slab solid-state lasers [PDF]

, 2009
In this paper, two new fabrication methods are developed for highly curved toroidal laser resonator mirrors based on laser micromachining of cylindrical substrates that already have the large lateral curvature RT provided by conventional polishing. These

Fiber-laser-pumped Ti:sapphire Laser [PDF]

Conference on Lasers and Electro-Optics 2010, 2010
We report the first experimental demonstration of efficient and high-power operation of a Ti:sapphire laser pumped by a simple, compact, continuous-wave (cw) fiber-laser-based green source. The pump radiation is obtained by direct single-pass second-harmonic-generation (SHG) of a 33-W, cw Yb-fiber laser in 30-mm-long MgO:sPPLT crystal, providing 11 W ...

Low spatial frequency laser-induced periodic surface structures in fused silica inscribed by widely tunable femtosecond laser pulses

Scientific Reports, 2022
The formation and evolution of laser-induced periodic surface structures in fused silica under irradiation of widely tunable (in the 1–3  $$\upmu$$ μ m range) linearly polarized femtosecond (200 fs) pulses was studied experimentally.
