Which materials can be effectively processed with lasers?

The choice indicating that metals, plastics, wood, and glass can be effectively processed with lasers is accurate because lasers possess the versatility and precision required to engage with a wide array of materials. Each of these materials has unique properties that allow for different laser technologies to be applied successfully.

Metals are commonly processed using high-powered lasers, which can cut, engrave, or mark them with great precision. Plastics can also be effectively cut or engraved due to their ability to absorb the laser energy, allowing for clean cuts without rough edges. Wood processes well with lasers, often showcasing intricate engravings or cuts, especially with CO2 lasers that are commonly employed for this purpose. Glass, while more challenging due to its reflective and brittle nature, can still be processed through careful laser methods that allow for engraving or cutting without shattering.

Other options suggest a limitation to specific materials, which does not reflect the broad capability of laser technology in material processing, thereby illustrating the expansive applicability of lasers across varying substrates.
