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.
