This leads to long patent disputes, with Gould only receiving patents in 19. Almost at the same time in 1958, Townes publishes a paper that shows that masers could operate in the optical and infrared spectrum. 1957 – Gordon Gould theorizes the laser.In 1954, he demonstrates that the maser works with a device that emits a wavelength of ≈1 cm. 1951 – Charles Hard Townes conceives the maser (microwave amplification by stimulated emission of radiation), the predecessor of the laser (light amplification by stimulated emission of radiation).1917 – Albert Einstein theorizes that electrons can be made to emit light of a specific wavelength in his paper “On the Quantum Theory of Radiation”.Here are some of the key events that led to the invention of laser etching as we know it today: Since the two processes are very similar (laser engraving involves some level of melting), the origin of laser etching is arguably the same as laser engraving. The date laser etching was invented is unknown but we know that laser engraving was reported to be used for the first time in 1978. This can color the material in black, white or gray.Įtching is most commonly used to produce permanent markings such as data matrix codes, serial numbers, barcodes and logos. As a result, the surface of the material melts and expands. To produce a raised mark, the laser beam delivers a high amount of energy to a small area. Highly versatile, it can be used with most metals. It is part of the broader category called laser marking which also includes laser engraving and laser annealing. Laser etching is a process that creates marks on parts and products by melting their surface.

Whether you want to know how it works, how it’s different than other laser marking processes or how much it costs, we’re confident that you will find everything you need to know in this article. Over the years, we’ve been asked all kinds of questions about it. Because of its speed and durability, laser etching is the process that we recommend for most marking applications.
