We performed shallow engraving on the surface of a 150μm thick ultra-thin cover glass using a femtosecond laser.
On the WEB page, you can see that the edges of the recessed areas and the unprocessed areas, which were processed in circular and cross shapes, are cleanly finished without cracks or melting. Unlike conventional lasers, where light can pass through and processing cannot be achieved, or contact processing, where the workpiece may crack, this method avoids those issues.

basic information
The surface roughness before processing is approximately Sa=0.01, but after processing, it becomes around 0.2, resulting in a cloudy surface. Please use it in various situations such as controlling light transmittance and decoration. Of course, ultra-short pulse laser processing can also be applied to various transparent materials and brittle materials, including quartz glass, optical glass, sapphire, and others, in addition to borosilicate glass.

Company information
At Lips Works Co., Ltd., we provide contract micro-fine processing using ultra-short pulse lasers, as well as the design and manufacturing of laser systems. In our contract processing business, we have been quick to engage in the development of industrial ultra-short pulse lasers and have been involved in contract micro-fine processing using these lasers. We specialize in applying fine periodic structures (microtextures) to work surfaces aimed at controlling tribological properties, optical properties, and release/adhesion characteristics. We can accommodate requests from small-scale prototypes to mass production according to our customers' needs. In our system engineering business, we leverage the laser processing technology cultivated in our job shop to provide a comprehensive service from selecting laser oscillators suitable for applications, designing optical systems, devising fixtures and auxiliary equipment, to system integration. We assist in improving the precision and efficiency of the processing required by our customers. As experts in laser technology providing cutting-edge laser processing techniques, we strive to be a valuable resource for our customers, so please feel free to contact us.
