In our standard procedures, we must create devices that are even more precise and enable us to use light in a manner that is safe and efficient. This is our expertise in the field of photonics;\n\nRounded out by use of the \u201cfemtosecond laser\u201d, an industrial tool that can modify surfaces through interaction with light and can also
