Back to the Future July 22 2014

Our yttrium and erbium ingots are next up to be etched, starting tomorrow.  Both of these metals are used in YAG lasers, which is what our ingots are etched with. The high intensity and precision of the YAG laser beam is necessary given the exceptional density and hardness of several of our metals and our desire to have them cleanly and crisply etched.  In the absence of an annihilation reaction or the formation of a black hole when the yttrium laser meets the yttrium ingot (neither of which we expect), we'll have our first rare earth ingots available in August.  Should I end up in 1955 driving a DeLorean, searching for fuel for my flux capacitor and waiting on the next thunderstorm, we may be a little delayed.
