“…In contrast to inorganic materials (such as stone), laser irradiation of bio-organic materials (such as paper) may lead to photochemical and photothermal degradation.

A systematic experimental study applying nanosecond laser pulses with 532 nm radiation to a specially selected set of historical paper samples exhibiting a broad range of composition and origin was undertaken to develop a quantitative irradiation dose model. This allows the optimisation of laser pulse number and fluence in order to maximise cleaning efficiency while excluding substrate modifications such as yellowing or destruction.

“…Pulsed lasers, especially short pulse lasers, have been proved to be an efficient way to process not only common engineering materials but also hard-to-process biomaterials, such as heart tissue, teeth, and cornea. 1 Even some researchers studied laser interaction with cellulose, gelatin and papers [2][3][4] for possible practical applications. In spite of its huge potential importance in many disciplines, however, laser interaction with plant leaves have not been studied to date.…”

In this article, we investigate how 355, 532, and 1064 nm picosecond lasers interact with grass tissues. We have identified five interaction regimes, and based on this classification, interaction maps have been constructed from a systematic experiment. The optical properties of light absorbing grass constituents are studied theoretically in order to understand how and how much light is absorbed by grass tissues. Scanning electron microscopy and optical microscopy are employed for observing morphological and structural changes of grass tissues. To the best of the authors' knowledge, this is the first investigation into laser interaction with plant leaves and reveals some fundamental findings regarding how a laser interacts with grass tissues and how plant leaves can be processed using lasers.

“…The paper surface damage or irreversible changes of the substrate structure and the chemical composition often result from the sequence of these ordinary cleaning procedures. The use of pulsed laser radiation for cleaning and restoration of historical documents and artworks has recently been proposed [2][3][4][5][6][7][8][9]. This technique allows avoiding negative effects found when using mechanical and chemical procedures to remove paper impurities.…”

Laser cleaning and restoration of documents on the paper base offer advantages over traditional mechanical and chemical cleaning methods. In this work, the office-type paper artificially contaminated for research purposes was cleaned with subnanosecond laser pulses. Laser cleaning recovered more than 80% of the paper initial brightness observed in the visible range, whereas chemical modifications of the paper studied by the FTIR spectrometer were below the spectrometric noise level. The laser fluences above the optical breakdown threshold of the paper surface resulted in the uplift of the paper surface and thinning-out of cellulose fibres in the breakdown zone. This type of morphological modification is accompanied by the FTIR detected compositional changes of the substrate -the intensity of three CaCO3 infrared peaks decreases after laser treatment.
