A method for measuring the laser plasma flow field on the surface of a target with the use of a laser synchronous interference system is presented. A measuring theory for plasma parameters including temperature, pressure, density, and ionization degree is built. An interference measurement for laser plasma produced by a Q-switched Nd:YAG laser acting on an Al target surface has been made, and results are given for the plasma parameters. © 1997 John Wiley & Sons, Inc.

An analytical method for treating the problem of laser heating and melting is developed in this paper by suggesting a simple and reasonable temperature profile form. Temperature distributions in material before melting as well as after melting are given, and the movement of the phase interface is also obtained. As an illustrative example, computations are carried out on silicon material, and the results are in good agreement with those obtained by other authors. © 1997 John Wiley & Sons, Inc.

We develop a method to measure the evolution of the temperature of laser-induced plasma during the initial period by using a plasma flash. The plasma emission is considered as blackbody radiation during the first detonation stage, and bremsstrahlung radiation during its expansion period. Based on the Planck formula and the bremsstrahlung radiation formula, the plasma temperature evolution during the initial period is obtained, which is helpful for the presented measurement methods to determine the temperature evolution during the entire process. © 2000 John Wiley & Sons, Inc.

The interaction process of laser and MOS-type charge-coupled devices (CCD) has been analyzed in brief. Several kinds of damage thresholds, including optical breakdown threshold, direct damage threshold, and laser energy threshold (which leads to complete failure of the device) produced by a Q-switched Nd:YAG laser have been put forward and obtained experimentally.
