Abstract: Old books and prescriptions are manuscripts which relate us to the past, so it is necessary to maintain them. Concerning that potential capacities of laser and its application for maintenance and restoration of different monuments has proved, we decided to recognize paper and stain in Herzberg introducer and systemic analysis of SEM, ATR, and PIXE and also study perishing of paper stain. In this study we explain tested cases by others and superiority using of laser than current chemical and mechanical ways and also we use from four laser types including: a- Dye Laser (whit 565nm wave length), b- Argun (with 515nm wave length), c- Nd:YAG (with 1064, 532 nm wane lengths) and d- Copper Steam (with 578, 510 nm wave lengths). By studying before and after to shine onto the laser radiate on the stain in PIXE analysis it is determined that among applied lasers in this study, the Nd:YAG laser with 532nm wave length is more appropriate for perishing stain of paper works.
