On the heat transfer of the electron beam window of a gas laser
Zhen Chenen
The heat transfer equation for electron beam window foil was solved taking into account the effect of heat exchange on the gas bourdary layer under the approximate bourdary condition at room temperature. Based on the solutions, the limitations to output beam intensity imposed by the window foil due to the heat effect wThe heat transfer equation for electron beam window foil was solved taking into account the effect of heat exchange on the gas bourdary layer under the approximate bourdary condition at room temperature. Based on the solutions, the limitations to output beam intensity imposed by the window foil due to the heat effect were discussed respectively for pulsed or CW output of electron beams..

Continuously tunable laser from IR to X ray by relativistic Doppler effect of high energy ion beam in negative temperature state
Li Fuli
It is shown that a laser will be continuously tunable from infrared to x-ray by relativistio Doppler effect of high energy ion beam in negative temperature state. The tunable range is △vT=2v’βγ. The threshold and parameters of lasers are considered. The methods to excite ion beam selectively are suggested.It is shown that a laser will be continuously tunable from infrared to x-ray by relativistio Doppler effect of high energy ion beam in negative temperature state.

Analysis of sandwich holography and its feasibility test
Li Huayu, and Di Jianhua
Following problems are discussed in this report: 1) It is proved by analysis that the regulation sensitivity of sandwioh holography is much lower than that of double plate holography. 2) The dependence of regulation sensitivity on the parameters of optical path are given. 3) For reference plane wave, it is proved that Following problems are discussed in this report: 1) It is proved by analysis that the regulation sensitivity of sandwioh holography is much lower than that of double plate holography. 2) The dependence of regulation sensitivity on the parameters of optical path are given. 3) For reference plane wave, it is proved that there is no distortion of image as certain approximate conditions are satisfied. 4) It is indicated that both sandwich and double plate holography have inherent defect of additional error because of the optical inhomogeneities in the substrate of the holographic plates..
