CO 2 laser with the advantages of high energy density, short process period, non-pollution, etc. could be applied as a novel thermal treatment for wooden and bamboo materials processing. Thermal modification is widely used for bamboo materials as an efficient modification method. Rongrong Li, a,* Jingjing Chen, a and Xiaodong (Alice) Wang b Prediction of the Color Variation of Moso Bamboo during CO 2 Laser Thermal Modification This approach will be useful for selecting suitable and desirable processing arguments to get the surface color of bamboo productions. The quadratic models of ∆L* and ∆E* created by response surface methodology were competent for describing the relationship between laser processing arguments and color indexes of ∆L* and ∆E*. The results showed that the increase of laser power had a positive influence on increasing the absolute values of ∆L* and ∆E*, but the feed rate of laser emitter and sweep width increasing had opposite effects on absolute values of ∆L* and ∆E*.
Response surface methodology was chosen for designing experiments and modeling.

The lightness variation and total color variation (∆L* and ∆E*) were collected using a portable colorimeter to describe the bamboo surface color variation after laser irradiation. The laser intensity argumentation of power, motion arguments of feed rate, and sweep width for laser emitter were selected as input arguments for treating the Moso bamboo surface. could be applied as a novel thermal treatment for wooden and bamboo materials processing.
