Grating-assisted fabrication of sub-wavelength ripples during fe... ... an important role. In this Letter, the effects of grating structures on the distribution of the absorbed laser intensity, SP-laser coupling, free electron distributions, and ablation shapes are investigated by the plasma model, taking into consideration ...
In vivo imaging of mice auricle vessels using adaptive optical c... ... signals in vivo. Vessels of mice auricle at 80, 100 and 120 μm depth are obtained, and image contrast and fluorescence intensity are significantly improved with AO correction. The typical 10%–90% rise-time of the metric value measured is 5.0 s for a ...
Multiscale analysis of single- and multiple-pulse laser-induced ... ... coatings are performed at 532 nm. For single-pulse irradiation, the damage is attributed to the defects and the electric intensity distribution in the multilayer thin films. When the defect density in the irradiated area is high, delamination is observed. ...
Simultaneous 3D temperature and velocity field measurements of m... ... micro-digital holographic particle tracking velocimetry. A diffraction-based model is applied to analyze defocused particles to determine the intensity ratio of two fluorescent dyes on the particle. The model is validated with experimental images. As the ...
Diode-pumped Nd:YLF slab master oscillator power amplifier laser... ... power amplifier 1053 nm laser system is demonstrated. We design a home-made pump module to homogenize the pump intensity through the ray tracing method. To increase the extraction efficiency, the pre-amplifier adopts a double-pass amplification structure ...
Total Variation Based Dce‐Mri Decomposition by Separating Lesion...This study aims to obtain the accurate time intensity curve (TIC) of a dynamic contrast-enhanced magnetic resonance image (DCE-MRI) by eliminating the normal tissue enhancement and obtaining pure lesion information. The TIC of DCE-MRI is sometimes ...
Chirp control of femtosecond laser-filamentation-induced snow fo... ... great impact on airflow motion and snow formation. The experiments show that snow formation mainly relates to the filament intensity distribution. Negative chirped pulses produce a greater amount of snow because of higher intensity inside the filaments as
Modulating Photonic Crystal Structures to Generate Optical Frequ... ... generate an optical frequency comb (OFC) generation is to cascade intensity and phase electro-optical modulators [1]. Nanoscale all-optical devices can also achieve intensity and phase modulation, however the use of these modulators to generate OFCs ...
