Stainless steel-doped SrTiO3 thin films were fabricated by laser molecular beam epitaxy (L-MBE). Nonlinear optical property of the thin film was measured by the single beam Z-scan technique at the wavelength of 532 nm. Two two-phonon absorption coefficien
Reconfigurable time-stretched swept laser source with up to 100 MHz sweep rate, 100 nm bandwidth, an
The sweep rate, sweep range, and coherence length of swept sources, respectively, determine the acquisition rate, axial resolution, and imaging range of optical coherence tomography (OCT). In this paper, we demonstrate a reconfigurable high-speed and broa

Crystallization is induced by pulsed laser irradiation of as-deposited amorphous Ge2Sb2Te5 films. Changes of the irradiated areas have been analyzed with the reflectivity contrast. As laser fluences increasing, the reflectivity contrast increases from 0%-
本文报道了一台使用UV自动预电离,C-C转移放电泵浦的XeCl准分子激光器,并且以激光器放电信号和输出激光信号的同时测量结果为依据,分析了激光器放电的能量沉积过程.可为设计同类型准分子激光器提供一些参考数据.
越来越多的医生、按摩师和化妆师把激光技术作为对付面部皱纹的一种新武器。虽然还不清楚为什么这种办法能起作用——或者说即使它起作用的话一现在估计美国全国有100个开业医生采用了激光消除皱纹的技术。
