Gain medium the gain medium is the major determining factor of the wavelength of operation,and other properties of the laser.There are hundreds if not thousands of different gain media in which laser operation has been achieved.the gain medium is excited by the pump source to produce a ...
Investigated are optical, luminescent and light-technical properties of the CdWO₄ and Bi₄Ge₃O₁₂ single crystals doped with mercury-like Bi³⁺ and Pb²⁺ impurities, respectively, with the aim of assertaining the p... Y Zorenko 被引量: 1发表: 2000年 ...
The degenerate two- and three-photon absorption properties of a multi-branched chromophore were investigated in the femtosecond regime utilizing white-light continuum and nonlinear transmission techniques. The experimental results show that the studied multi-branched structure exhibits relatively strong and br...
Clarifies the physical properties behind certain nonlocal electron conductivity models and shows how to choose the correct one for thermal filamentation. Three-dimensional fluid model of light filamentation in laser-produced plasmas developed by R.L. Berger et al.; Difference in the treatment of ...
Transport properties of HM/FM heterostructures We further pattern the as-deposited and freestanding HM/FM heterostructures into Hall-bar devices to measure the transport properties. The Hall conductance is measured with current injected along the x axis, whereas the applied magnetic field is rotated ...
Background: Various imaging properties of scanning laser ophthalmoscopes (SLO) such as contrast or depth discrimination, are superior to those of the traditional photographic fundus camera. However, most SLO are monochromatic whereas photographic systems produce colour images, which inherently contain infor...
鈻We discuss the properties of Geiger-mode avalanche photodiodes (APDs) and their use in developing an imaging laser radar (ladar). This type of photodetector gives a fast electrical pulse in response to the detection of even a single p... BF Aull,AH Loomis,DJ Young,... 被引量: 411发...
We designed a head-mounted three-photon microscope for imaging deep cortical layer neuronal activity in a freely moving rat. Delivery of high-energy excitation pulses at 1,320 nm required both a hollow-core fiber whose transmission properties did not
The angular and temporal axes are two basic elements in the plenoptic function P(spatial: x, y, angular: u, v, wavelength:λ, time: t), which completely characterizes the fundamental properties of light. With decades’ investigations and developments, current 3D imagers have reached the practica...
Properties of NCHCFs made from silica glass for light transmission in mid-IR are investigated, in particular, the influence of the cross-section geometry on optical properties and the core-cladding mode coupling due to bending. AF Kosolapov,AD Pryamikov,GK Alagashev,... 被引量: 7发表: 201...
