Abstract The organic contamination damage of large-aperture optical components limits laser energy improvement inertial confinement fusion (ICF). In situ cleaning via low-pressure plasma is expected to remove contaminants from the surface. Herein, air equipment was proposed and used on surfaces SiO 2 sol–gel antireflection (AR) films in by conducting experiments. Its electrical discharge parameters were investigated optimized during cleaning. Plasma diffusion characteristics homogeneity...
Abstract Low-pressure plasma cleaning technology is currently regarded as a highly promising method for the effective in-situ removal of surface contaminants from large-aperture optical components (LAOC) (⩾430 mm) in laser fusion facilities. After long cleaning, irreversible damage can occur to sol-gel antireflective (AR) coatings on LAOCs. Hence, study was conducted analyze characteristics low-pressure and implement techniques facility. Initially, impact organic contaminant levels...
K9 glass is prone to developing color center defects under gamma irradiation, which exhibit strong absorption at specific laser wavelengths. However, most of these centers an annealing phenomenon in natural environmental conditions, wherein their absorptive characteristics gradually diminish or even disappear. Hence, this study proposes employing a high-temperature accelerated approach address the induced by aiming attain stable for Initially, experiments were conducted generate using...
Abstract Optical computing, leveraging light propagation as engine, has emerged a promising paradigm due to inherent advantages in parallel processing, high throughput, and energy‐efficient. However, Existing diffractive network architectures are typically designed for single‐wavelength illumination, limiting their ability capture multiscale spatial‐frequency features of input objects. Here, dual‐wavelength differential neural () is proposed, which synergistically integrates complementary...
The spatial distribution characteristics and large-aperture surface treatment capability of low-pressure non-thermal plasma have garnered significant attention. Consequently, there has been a concerted effort to enhance the performance these systems with aim broadening their applicability across range fields. This study systematically investigates 50–60 Hz using Langmuir probe diagnostics, controlled power (50–200 W) pressure (10–50 Pa) conditions. Key findings reveal that reducing chamber...
