Lithium Heat Pipe Oven?

Okay, we all know it's pretty darn hard/expensive to change a laser's wavelength at room temp, but what about using a lithium heat pipe oven?
I found this, but it doesn't go too in-depth. So I was wondering if anyone had any more information? I'm new to the actual physics behind lasers,
so sorry for the possibly n00b post, but I couldn't find anything for the life of me.

Seriously, no one?

I don't think you understand the goal of, or any of the physics involved in, the thesis you linked. It's a fluorescence study, that's all. They used an ECDL as a stabilized, controllable, and precise pump source. The oven is to vaporize Li metal because you can't get visible wavelength fluorescence from non-vapor phase metals. It has nothing to do with changing the output of the laser.

Haha, nope, I understand none of it . I guess I just misinterpreted it.
