Our team are engaged in the research of laser technology. They now use a laser gun for reading barcodes. Examples of laserlaser The optimal position of the focal spot was found to be at the distance of 6 mm before the laser-produced plume. On the interaction of femtosecond laser pulses with cluster targets. After the recording and the developing, the hologram was returned to the second holder and moved into the laser beam line. Figure 6 shows the temporal behavior of the radiation temperature and the laser pulse shape. The entrapment of radiation will make a photon be emitted and resonance-reabsorbed many times inside the laser material. In this process, the energy absorbed by the electrons during the interaction with the laser pulse is converted into both radiation and ion kinetic energy. Nonlinear confining and deconfining forces associated with interaction of laser radiation with plasma. Supersonic ionization wave driven by radiation transport in a short-pulse laser-produced plasma. Nonlinear confining and deconfining forces associated with the interaction of laser radiation with plasma. Characteristics of ion emission from plasma produced by high-energy short-wavelength (438 nm) laser radiation. Fine structure of parvocellular receptive fields in the primate fovea revealed by laser interferometry. Simple method for reducing the depolarization loss resulting from thermally induced birefringence in solid-state lasers. The results could be of relevance for the next generation of laser-plasma systems. Both experimental and calculated dependencies of burnthrough time versus foil thickness compared with laser pulse-form. The shock transit time for a given target thickness was determined from the peak of the laser signal. These examples are from corpora and from sources on the web.
