Say that I have a neodymium doped yttrium aluminum Garnet (Nd:YAG) laser crystal rod. If i'm using this crystal in a laser, will the size of the crystal affect any characteristics of the laser itself. That is, will a laser containing a 4-by-7 mm Nd:YAG rod operate differently than a laser containing a 20-by-35 mm Nd:YAG rod? I would imagine that it doesn't.

The spectral characteristics won't change, but the amount of (lasing) power you can get out will scale with the size of the crystal.

This what is was thinking. However, I was recently told that changing the crystal size would affect the lifetime. When I get a chance I'll link the thread. Thanks for the response.

Please continue the discussion in the other thread. Multiple threads about the same question are not helpful.
