Laser modification of tobacco leaves

Abstract

Our work concern is to adequately mark products in the cigars industry using a laser engraver. The work show the possibility of marking flexible and delicate material without destroying the item itself. In this method, a marking image is accomplished with two axes high speed system that direct the laser energy across the target surface. The lens assembly focuses the laser energy to achieve the highest power density on the work surface while maintaining the focused spot travel on a flat plane. The laser can be regulated to different intensities and/or translation speeds during the marking process to achieve different levels of contrast within a particular design.
