Laser is a device that emits a beam of coherent light through an optical amplification process. A laser can be considered as a system which stores light energy and releases it in a much localized area, the emitted energy has very high density energy. Laser Marking, also known as laser engraving or laser etching, is a marking method which utilizes laser light to mark materials using a fine spot diameter ranging from 0.002' to 0.01'. The laser marks with short pulses (30 nanoseconds), ... Read more
