Laser cleaning is reliable, fast, energy and material-efficient technology used for surface cleaning. Rust, coatings, paint, oils and many other unwanted materials can be quickly and efficiently removed. No abrasives or chemical compounds are consumed during the process, what makes this technology user and environment-friendly. Due to quick and rare servicing time it is widely used in material processing. Laser cleaning compared to existing conventional technologies such as sand blasting, dry ice or chemical cleaning is highly effective, economic and sustainable solution. Technology payback time is approximately one year assuming one shift operation. Portable systems include laser cleaning machine equipped with desired length optical fiber and a laser gun. Available output power is in range of 20-1000 W. Depending on output power, these systems are used for applications ranging from small surface treatment that requires high precision cleaning, to the removal of thick material layers on various types of substrates
