The mission operations planning assistant [PDF]
The Mission Operations Planning Assistant (MOPA) is a knowledge-based system developed to support the planning and scheduling of instrument activities on the Upper Atmospheric Research Satellite (UARS). The MOPA system represents and maintains instrument

Beyond Barniz de Pasto Mopa-Mopa Objects: Artisans and Harvesters in the 21st Century
HeritageThis article intends to highlight and reconstruct the relationships between humans (harvesters, woodworkers and master artisans) and non-humans (raw materials, tools, places, products, etc.) in the Barniz de Pasto mopa-mopa tradition. These relationships were lost when the focus came to be primarily on the objects, as happens in most popular art forms ...

Journal of Extracellular Vesicles, Volume 14, Issue 6, June 2025.ABSTRACT Xylella fastidiosa (Xf) is a Gram‐negative bacterial plant pathogen responsible for severe diseases in a variety of economically important crops. A critical aspect of its virulence is the production of extracellular vesicles (EVs). In this study, we discovered that DNA‐binding proteins and nonribosomal RNA‐binding proteins are abundant in the ...

In the wake of the erbium-doped fiber amplifier - functional fibers and their impact
, 2005 There have been a number of laser developments in recent years that are quite staggering in their simplicity, that are so powerful in their operation that engineers and scientist have to rethink the laser future.

An all-fibre PM MOPA pumped high-power OPO at 3.82 microns based on large aperture PPMgLN
We report a large aperture PPMgLN based OPO generating 21W of average output power at a slope efficiency of 45%, pumped by the output from a polarization maintaining Ytterbium doped fiber MOPA operating at 1060nm producing 58W of average output power and

Macromolecular Symposia, Volume 414, Issue 3, June 2025.Abstract The study deals with the effects of laser surface treatments on the fatigue behavior of adhesive‐bonded aluminum joints. Laser texturing, laser cleaning, and their combination are produced by adopting a 30 W nanosecond pulsed Yb:YAG laser. Parallel grooves, perpendicular to the load direction, varying in depth, width, and areal density are ...

Green-pumped, picosecond MgO:PPLN optical parametric oscillator
, 2011 We investigate the performance of a magnesium-oxide-doped periodically poled lithium niobate crystal (MgO:PPLN) in an optical parametric oscillator (OPO) synchronously-pumped by 530nm, 20ps, 230MHz pulses with an average power of up to 2W from a ...

Characterization of emission regimes in a 1.5 um high brightness MOPA [PDF]
, 2014 We present and analyze experimental results on the emission characteristics of a 1.5 ?m distributed feedback tapered master-oscillator power-amplifier in a wide range of steady-state injection conditions, showing different emission regimes under cw ...

Advanced Photonics Research, Volume 6, Issue 4, April 2025.By leveraging the TDF and HDF ASE spectral‐beam combination scheme, a 2.0‐μm‐broadband fiber ASE source is obtained with a maximum output power of 10.9 W, an full width at half maximum of 67 nm, and a spectral range of 176 nm. Herein, Tm‐doped fiber (TDF) amplified spontaneous emission (ASE) and Ho‐doped fiber ASE to realize a high‐power, 2.0‐μm ...
