The Compact Q-switched DPSS Lasers source can mark on glass

It is not uncommon to use a laser marking machine to code glass. With the progress of the times, there are more and more styles of glass. Using a laser engraving and marking machine to process customized glass can display more personalization and realize the engraving. High precision level. We all know that glass is fragile, so too much force cannot be generated in the carving, otherwise it will cause the glass to break. So, what are the laser marking machines that can code on glass?

Glass is very common in various fields. The glass engraved by the laser marking machine can better show the texture of the glass, and the engraved pattern gives people a feeling of being ready to show. Glass has been marked by various forms of traditional techniques for centuries. Unfortunately, this method has many drawbacks. The mechanical force exerted by the scoring tool can cause micro-cracks in the glass and subsequent breaking steps can cause Small nicks and chips, since the glass is particularly prone to breakage, it is already difficult to use traditional engraving methods at this time.

At present, there are two kinds of engraving on glass, one is CO2 laser marking equipment, also called carbon dioxide laser marking machine; the other is ultraviolet laser marking equipment. Because pulse and spot size are important parameters in glass laser marking. Because the shorter laser pulse can limit the heat flux to spread in a smaller area. Although glass absorbs excimer laser wavelengths and thus can be used for glass marking, the use of masks prevents real-time generation of 2D barcodes.

In fact, CO2 laser marking machine and UV laser marking machine use non-contact processing technology, which greatly avoids the problem of fine cracks and chips. Suitable for laser marking on glass is a CO2 laser marking machine with an output wavelength of 10.6μm and a quadruple frequency UV laser marking machine with a wavelength of 266m.

Some people will ask: Can fiber laser marking machine code on glass?

It is very clear to tell you that no, neither can tempered glass, the wavelength of the laser is different, and the wavelength of the fiber optic machine is 1064nm. At the same time, the optical fiber marking machine cannot focus light on the glass.
