Using a picosecond laser with the same spot diameter for SUS and PI, we processed five types of grooves with different depths.
The five grooves in the image are all processed with a target width of 15μm. Even if the entrance width is the same, you can see that the cross-section changes from a U-shape for shallow grooves to a V-shape for deep grooves. Similarly, when the material changes from metal to resin, the change in cross-sectional shape can also be observed.

basic information
Even with processing using lasers of the same thickness, the groove shape will change depending on the number of irradiations and the groove depth. We can propose specifications and dimensions according to the desired shape, such as V-shaped grooves with cracks or grooves that emphasize the curvature of the bottom surface. Please feel free to contact us if you have any concerns regarding groove processing or scratch creation.

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.
