A laser cutter is a machine that uses a high-powered laser beam to cut, etch, or engrave a variety of materials, including wood, plastic, metal, and glass. The laser beam is focused and directed by a series of mirrors and lenses, which can achieve very precise cuts with a high level of accuracy.
The laser used in a laser cutter is typically a CO2 laser, which produces a beam of infrared light at a wavelength of 10.6 micrometers. This wavelength is absorbed by many materials, causing them to melt, vaporize, or burn, depending on the power and duration of the laser beam. The laser can be controlled by a computer program, which allows for complex designs and patterns to be created and cut with great precision.
Laser cutters are commonly used in industrial manufacturing, but they are also becoming more popular among makers, artists, and hobbyists due to their versatility and ease of use. They can be used to create intricate designs, cut out parts for prototypes or models, or even engrave personalized designs onto a variety of materials.
