100W 200W 300W laser cleaning machine can be used to clean the surface of wood, but the cleaning effect can be influenced by factors such as the type of wood, surface treatment, and the configuration of the laser cleaning machine. In general, for wood cleaning, both single-mode and multi-mode lasers can be used, but the choice of laser type should depend on the specific cleaning task.

When marking on HDPE plastic, it typically involves changing the color beneath the material's surface, often through carbonization. With the use of an ultraviolet laser marking machine, creating dark marks can be achieved by selectively carbonizing the sub-layer of the plastic surface.

Compared to single-mode pulse lasers, multi-mode pulse lasers have a more uniform energy distribution in their beam profile, approaching a flat-top beam mode. This characteristic makes multi-mode lasers less likely to cause damage to the substrate during cleaning processes.

Currently, the two main types of fiber lasers used in industrial marking applications are Q-switched lasers and MOPA lasers. Both have a significant market share, and they excel in their respective processing areas. However, there is a common misconception in the market that MOPA lasers can completely replace Q-switched lasers. Let's compare the parameters of Q-switched and MOPA lasers
