In the case of laser marking, for example, a changing or non-optimum beam profile may mean that one letter is deeper than the next, and in refractive eye surgery it may have more serious consequences.
An initiative called Breakthrough Starshot wants to explore another star system using ultra-powerful laser beams and wafer-thin spaceships. It's a goal that sounds so fantastic, you'd be forgiven ...
The electrons in the beam interact with the electrons bound to the metal atoms to create X-rays," he said. "At NIF, we use the high-power laser beam instead of an electron beam to make the X-rays ...
Material processing applications include cutting, welding, drilling, marking, rapid prototyping and photolithography ... It briefly describes the basic principles of laser beam welding, the different ...
