Plant leaves are multi-component optical materials consisting of water, pigments, and dry matter, among which water is the predominant constituent. In this article, we investigate laser interaction with grass using CO2 Er:YAG lasers theoretically experimentally, especially targeting in tissues. We have first studied properties light absorbing constituents theoretically, then identified regimes constructed maps through a systematic experiment. Using maps, how change as process parameters varied. This study reveals some interesting findings concerning carbonization ablation mechanisms, effect beam diameter, efficiency quality lasers.
