Broad area laser diode (LD)filamentationfacet phase distributionNFPFFP.In a broadarea laser diode (LD) having a wide stripe width, a Gaussian pattern is not obtained in the near field (NFP) and the far field pattern (FFP) has multiple peaks, which is known as filamentation. Thus, when ...
First, Au-nanoparticles generates plasmons under the radiation of laser, this environment can greatly enhance the electromagnetic field around the metal nanostructures. The plasma-enhanced electric field changes the dominant absorption mechanism of laser, which is dominated by the multiphoton ionization ...
Synchrotron radiation is having a very significant impact on the many disciplines that make use of the radiation in the x-ray, vacuum ultraviolet, and infra-red regions of the spectrum. The rapidly increasing demand for beam time at existing facilities, the construction and commissioning of new ...
Integrated linear injection-laser arrays were made from AlGaAs/GaAs heterostructures grown by MOCVD epitaxy. The total width of the emitting surface was 1 cm and the arrays were intended for the pumping of solid-state lasers. The watt—ampere characteristics, the overall efficiency, the emission sp...
We have obtained the single pulse laser oscillation with 400±10 ps pulse duration at 311 nm from LiLuYF:Cecrystal with 6 ns laser pump at 289 nm. We expect this due to passive Q-switch by means of pump induced color centers which absorb laser radiation and determine the intensity discrimi...
high density of pure soft X-ray radiation (without plasma expansion fragments)with broad-band spectral range can be obtained at the focus of the lens.As laser-plasma is considered,the radiation density of 1.3×10~5 W/cm~2 is obtained,the transmission coefficient is 18.6%, the ratio of the...
An experimental method was developed for the study of dynamics of the establishment of the spectral, power, and spatial characteristics of the radiation emitted by injection lasers with good spectral (~0.1 nm), temporal (~2×1010 sec), and spatial (~1 μ) resolutions. An investigation was mad...
