If you like lasers, build an ion trap.

If you only like lasers a little bit, build an optically pumped standard.

If you *really* like lasers, build a fountain.

If you are more chemically inclined, there are a ton of gasses you
can work with, methane, amonia, CO2 etc.

The one thing nobody has done or even tried yet, (as far as I know),
is optically excite a solid crystal.

Never attribute to malice what can adequately be explained by incompetence.
