Turn plain stainless steel into shimmering diffraction art and almost-holograms. Applied Science used the Cloudray GM-100 NEO MOPA fiber laser to grow ultra-precise oxide patterns that bend light, create color, and reveal parallax when you move. With fine control over pulse rate and power, you can: • Write diffraction gratings with ~1 μm pitch • Color-mark stainless steel by oxide thickness, not paint • Import bitmaps into LightBurn and let Python scripts map every pixel to a grating “direction”
