Surface accumulation of ion-implanted tin in GaAs after laser annealing

Abstract: A Rutherford back-scattering study of ion-implanted tin in GaAs has been performed before and after irradiation with single pulses from a Q-switched ruby laser. Both indiffusion and segregation of tin to the surface occurred, the amount being dependent on the laser energy density and whether the beam was multimode or homogenised.

Physical Properties of Laser-Produced Dense Plasma in High-Pressure Argon Gases

Abstract: High-pressure gaseous argon at pressures up to 200 atm was irradiated by a ruby laser to study the physical properties of the laser-produced plasma. High-density plasmas with an electron density of the order of 1020~1021 cm-3 were obtained. At low pressure, a nearly complete ionized state was achieved, and as the gas pressure increased, the degree of ionization decreased. The electron temperature was of the order of 105 K and increased slightly with increasing pressure. The hot plasma was conical with its apex at the focal point, and the radius of the plasma depended only on the axial position. As the pressure increased, the plasma extended axially in front of and behind the focal spot. This phenomenon is interpreted as the result of a change in the refractive properties of the high-pressure gas.

Formation of highly compressed stimulated Brillouin scattering pulses in liquids

Abstract: Giant pulses (?l ? 30?50 nsec) from a ruby laser were shortened to 2.5?1.2 nsec by stimulated Brillouin scattering in a cell 1 m long filled with a liquid. In the case of CCl4 a reduction in the pulse duration by a factor of over 30 was achieved and the contrast of the Stokes pulses was found to be high.
