The breakthrough came with the replacement of the Nd:YAG laser by the modern diode ... And because screwing or gluing the parts together is expensive, laser welding becomes the best choice.

Nd:YAG lasers with harmonic generators; 100Hz Nd:YAG lasers; Air cooled Nd:YAG lasers; Tunable lasers from 0,2 mkm up to 20 mkm: OPO systems, Ti:Sapphire lasers, DFG; Diode pumped femtosecond lasers; ...

We doubt this process will be a mainstream method anytime soon, not least because it requires a 50-Watt Nd:YAG fiber laser. But it’s an interesting process that reminds us of [Zachary]’s other ...

pilots at a nearby airfield getting their retinas blasted out due to an absolutely harebrained idea to use a fairly high-powered Quanta-Ray Nd:YAG laser on reflective surfaces in the open.
