Yu Shusheng, Lou Qihong, and Du Longlang
UV preionization of pure He, Ng; Ar, NV and CO2 laser gas mixture were studied, by means. of a modified coaxial probe as positive probe. The experimental result shows that the photoelectron densities are increased by adding- moderate amqunts of tripropylanmine ia CO2 laser gas mixture.

A quantum theory for collective spontaneous emission of a multiatomic system with different resonance frequencies is, applied here to the superradiant emission of two groups of atoms undergoing two independent transitions. An analytical expression for the emmited intensity as a function of time is obtained after making rotating wave approximation, slowly varying envelope approximation and decorrelation approximation..

Semiconductor materials such as Ge and InP etc, were investigated by the laser-induced chemical photolithography with argon ion laser. Two kinds of thresholds of light intensities were observrd respectively for the scanning photolithography on the surface and the rapid penetrated etching. The former has a lower threshold and the latter higher depending on the matting point. There exists a complicated relation between the etching rate and the light intensity. The etching rate decreased with the increase of the etching depth. Semiconductor species with higher dopant concentration were etched faster than those with lower dopant concentration..
