3.9 Laser Cleaning
It depends on the blast of laser radiation that can remove dirt from the surface. It is
a quiet cleaning process without the need for solvent or abrasive. Fume generated
by ablation can be easily removed by vacuum. The old church, damaged during
WWII, in Dresden Germany was restored and every piece was reassembled after
laser cleaning. Old structures with toxic lead paints can also be cleaned by lasers.
4 Summary
Lasers are used for a wide variety of manufacturing processes. The main reason for its
popularity is its ease of availability with a wide range of intensity levels from fraction
of W/cm
2 to 10
15 W/cm
2 with precision. It is also amenable to automation, making
it a useful tool for modern manufacturing. It is one of the most adaptable forms of
energy sources for industry. Its popularity and applications have been continually
increasing since its invention.
