Extended breakdown of Simpleman approximation
... tilt angle between the distribution density peak and the main polarization axis. The tilt angle’s behavior changes with an increasing laser intensity. We show that this behavior change is directly related to the release time of the electron from the atom.

Research of hundred picosecond microjoule pump laser system
A master-oscillator power amplifier (MOPA) system based on Nd glass laser with output intensity of 5 GW/cm2 is described. The laser operates at 1 Hz with pulse energy up to more than 4 mJ. The spatial profile is near top hat and the diameter is 1 mm, the ...

在泵浦弄空情况下的喇曼效应
Focusing position in Raman cells for pumping light is adjusted carefully. The intensity for backward Stokes light is increased, and pump depletion is produced. Two isolated pulses appear for the forward Stokes light.

关于平面全息图反射波再现像的亮度
The ratio between the brightness of reconstructed images of the reflected and transmitting waves depends on the intensity ratio of the two waves. This paper studies the relationship between the mentioned ratio and the energy reflectivity on the reflecting ...
