Though lasers are ubiquitous in manufacturing, the vast majority of applications involve no depth control due to the inherent beam nature of light. Even the most deterministic of processes (like ultrafast micromachining) suffer from variability when scaled up to sufficient repetition rates and powers to provide material removal rates to meet industrial needs. Instead of trying to control the...
In partnership with the Royal Canadian Mint (RCM), a new laser colouring technique was developed using ultrafast lasers. The colouring of noble metals is initiated by laser ablation. We discuss the creation of nanoparticle arrays on the metal’s surface by the cooling of the plasma plume. The ablation is done in air, where the content of the plasma is re-deposited onto the metal’s surface. We...
