Propagation of a laser detonation wave was studied by two-wavelength Mach-Zehnder interferometry and laser-shadowgraph. To investigate the termination mechanism of the laser detonation wave, this study used a wedge nozzle and made a quasi-one dimensional propagation because the lateral expansion greatly influenced the LSD termination condition. We also investigated the dependency of gaseous form; N2 and O2. As a result, the velocity of the detonation front in O2 was faster than N2. The peak of the electron density profile in O2 was higher than that in N2. Furthermore, this distribution tends to increase when the position gets close to the target wall. This result has never been observed in two-dimensional situation.
