Abstract
A model is developed for the momentum transferred to a solid from a laser-supported gaseous detonation wave initiated in air above the surface. One-dimensional gasdynamic analysis is used for the detonation wave moving away from the surface and cylindrical blast-wave theory is employed to partially account for two dimensional effects. Momentum transfer coupling coefficients (impulse/laser energy) are calculated which are functions of the laser energy flux, pulse duration, and the beam and target surface areas. Results are compared with recent experimental data obtained using a high-power CO2 laser.
