The theoretical calculations present that the lowest and highest laser intensities are 3.5×10~(16) W/cm~2 and 1.6×10~(17) W/cm~2 to realize the amplification of NLK 32.8 nm X-ray laser induced by the circularly polarized laser,respectively. The evaluated laser intensity maybe overs 5×10~(17) W/cm~2 in the experiements.
The results show that the change of ionization probability with inter-nuclei distance is clearly influenced by the laser intensities of the fundamental field, but it almost keeps unchanged with different ratios of intensity.
The percentage of desorption ionization and the stability of primary structure of angiotensinⅠ(AnⅠ) were studied using different laser intensities with matrix-assisted laser desorption/ionization time-of-flight mass spectrometry.
Using a cross correlation between femtosecond laser and attosecond XUV, such profiles can be reconstructed from photoelectron energy spectra measured with two different laser intensities at 0° and 180° with respect to the linear laser polarization.
The appearance of the , CH+, C+ ions are at the laser intensities of 1.0×1014 W·cm-2,1.4×1014 W·cm-2 and 1.4×1014 W·cm-2, respectively. The facts show that dissociation of methane is a step wise process.
Soft X ray conversion efficiency from 0. 35μm laser-irradiated Al foil at different laser intensities on the "Xingguang Ⅱ" facility (energy 20J- 90J, focal spot ￣ 200μm, FWHM 400ps- 800ps) was obtained. A simple model was given to explain soft x ray conversion efficiency from 0. 35μm laser-Al plasma interaction.
The ablation parameters of laser plasma, especially line-shaped laser plasma have been discussed in detail, and their scaling laws with laser intensities have been demonstrated by theoretical analysis and calculation of experimental results directly using the ion measurement for the first time.
The model is used for the study of the influence of different parameters like laser gas temperature, gas mixture and pump rates on laser intensities of different rotational lines.
Ruby laser intensities exceedingI* - 1014 W/cm2 create a predominant acceleration of dense plasma due to nonlinear collisionless interaction resulting mainly from collective effects.
The possibility of using a combination of inducible and saturable absorbers, placed within the laser cavity, as a means of providing laser intensities confined to a narrow range centred about a pre-set intensity, is raised.
These results are consistent with stimulated emission (light quenching) of TPB at high laser intensities.
The stimulated Raman and Brillouin instabilities are studied for a variety of plasma conditions, drive laser intensities, and beam smoothing conditions.
The systematic study of a dynamic Burstein-Moss effeot by interband transition in Hg_(1-x)Cd_xTe (x=0.204) is reported. The experiments rely on the near coincidence between step-tunable transition from a CW CO_2 laser and energy gap of HgCdTe a~t 100K. The gross nonlinear effect is obtained at quite low laser intensities. A shift of the absorption coefficient with increasing light intensity is observed. The experimental results are compared with the theory of ours.
Ne pulsed two-step optogalvanic signals are obtained. The relation between two pumping laser intensities and oscillator strength of involving transition is discussed. The 1S_5→2P_2←1S_2 OG signal is investigated in great detail A comment on Shuker's explaination is made.
An experimental investigation of dual frequency tunable laser output from dye mixtures in ethyl alcohol pumped by a N_2 laser is described. The laser kinetic processes in the mixtures are analysed. The dual frequency laser intensities of the mixtures versus concentration of accepter dyes, and tuning range of dual wavelength laser in the mixtures are studied.
