Study of Mn laser ablation in methane atmosphere

Laser ablation of Mn target in vacuum and in the presence of CH4 was studied under 308 nm laser radiation. Time resolved emission using gated detection and scanning monochromator and absorption using the cavity ring-down spectroscopy were used to study vaporized plume. In the CH4 atmosphere we observed transitions identified as C2 and MnH rovibrational lines, while these spectral features were not detected in emission spectra. This is clear evidence of importance in combining both apectroscopic techniques in laser vaporized plume study.
