We did some research on YAG and fiber lasers.

The YAG's are physically huge and need lots of three phase power. They cost enough to make my eyes cross. They are also very inefficient.

The fibers are less expensive and use much less power but due to not being able to pulse at a low enough frequency, the give problems on silver and silver plated items. The few that were at the show were extremely low power, 5-10 watts.

I'm going to wait until the fiber laser industry matures a little bit.

If you have enough business and can install a machine that is about 8' long by 6' high, and have a lot of three phase power floating around, it might be worth getting into.
