The Bragg deviations proterties of volume holographic optical elements (HOEs) and compensation are Studied. And the allowable deviations of wavelength and angle from Bragg condition are discussed. Finally, tho authors como to a conclusion that at some modulations the higher diffraction efficiencies of VHOES can still be obtained off Bragg condition and the value of allowable Bragg deviation is larger in higher modulation. The experimental resulta are given in this paper..

Carrier-induced group-velocity dispersion influencing the chirped pulses propagating in traveling-wave semiconductor laser amplifiers (TW-SLA's) is analysed theoretically in this paper. The chirped pulses will be compressed or broadened because of carrier-induced group-velocity dispersion when TW-SLA operates far below saturation. The relations among the TW-SLA parameters, chirp parameters and broadening factors are investigated theoretically. The results imply that TW-SLA's provide the possibilities to compensate simultaneously for the effects of both fibre loss and fibre dispersion in optical communication systems when used asin-line amplifiers..

Using tho Stimulated Brillouin Scattering (SBS) in high pressure gas SF6 as a phase conjugating mirror in a Nd:YAG laser resonator, we have got laser pulses with the pulsa energy of about 100 mJ. The spatial mode of output beam is much better than the output beam from the phase conjugate resonator based on the SBS in liquids. The power density of about 150 MW/cm2. And nearly TEM00 mode are obtained. The stability of tho output energy is also increased..

In this paper, the steady state behaviour, linear stability and the response to small signal modulations of cavity length, pump and gain or loss of a sigle mode CO2 laser with homogeneously broadening medieum are analysed based on the vibro-rotational model.

We put special emphasis on the effect of the non-lising Vibro-rotation levels on the response of the three modulations mentioned above..

The experimental and theoretical investigations of the plasma produced by XeCl excimer laser evaporation of YBa2Cu3O7-aaaaaaaaaaaaaaaaa target are presented in this paper. The plasma emission spectrum was analysed with the Optical Spectrum Analyser (OSA) and a series of species in the plasma plume were resolved. Then the time-of-flight spectra of the species were measured using a monochromator with an optical fibre sampling system. An expansion model of the plasma plume was suggested on the basis of the experiment. By using the model, the time-of-flight spectra, the spatial characteristics of the plsma plume and the distribution of the superconducting thin film thickness deposited by the plasma were simulated. The calculaton results are in good agreement with the deposition experiments..

Effects of dipole-dipole interaction on the emission spectrum of atoms
[in Chinese], [in Chinese], [in Chinese], and [in Chinese]
The emission spectrum of a pair of two-level atoms coupled by dipole-dipole force in a single-mode radiation field is Studied. It is found that atomic dipole-dipole interaction destroys the symmetry of the spectrum. The spectral properties for the vacuum field and strong field are discussed in detail.
