Mechanism and application of laser cleaning: A review

The Fundamental Mechanisms of Laser Cleaning Technology and Its Typical Applications in Industry

“…The dominance of each mechanism is dependent on the optical penetration depths and the thermal diffusion lengths. In addition, the relative importance of each mechanism depends on the physical parameters, such as the laser cleaning medium, substrate materials, and contaminants [9,21]. Therefore, it is necessary to summarize the fundamental mechanisms of laser cleaning technology in detail.…”

“…The laser thermal stress mechanism is another mechanism discussed in the fields of laser cleaning. A schematic of the laser thermal stress mechanism is shown in Figure 2 [9]. Unlike the laser thermal ablation mechanism, the laser thermal stress mechanism utilizes the stress effect induced by the laser beam rather than the laser thermal effect.…”

“…Based on the interaction mechanism between a laser beam and materials, laser cleaning technology has been proposed for surface-cleaning purposes. Compared with common surface-cleaning technologies, such as mechanical cleaning, chemical cleaning, and ultrasonic cleaning, laser cleaning has the advantages of high precision and high efficiency, being environmentally friendly, producing low amounts of damage, exhibiting controllability, and having the potential to be used in a wide range of applications [9]. Therefore, laser cleaning is regarded as an advanced surface-cleaning technology and is expected to replace other surface-cleaning technologies.…”

Crystal growth and thermal properties of a LiY(MoO4)2 crystal

“…Lasers have been extensively applied in the fields of science, biology, industry, communication, medical treatment, and amusement. [1][2][3][4][5][6][7][8][9] The laser medium is one of the key components for lasers. Solid-state lasers, which are based on crystals, are widely used due to their compact structure and stability.…”

An empirical experimental investigation on the effect of an external electric field on the behaviour of laser-induced cavitation bubbles

“…3,4 Zhu et al recently wrote a comprehensive review on the mechanism and applications of laser cleaning which outlines an entire timeline of laser cleaning. 5 Over the years, cavitation has been applied to medical technology, especially in fields such as ophthalmology, 6,7 biomedicine, 8,9 and drug delivery. 10 Recently, micro fluidic techniques have been enhanced using cavitation, 11 and have been used in nanoparticle synthesis.…”
