The discussion revolves around the effects of crystal size on the characteristics of neodymium doped yttrium aluminum garnet (Nd:YAG) laser crystals. Participants explore whether different sizes of Nd:YAG rods, specifically comparing smaller and larger dimensions, influence the laser's performance, including power output and spectral characteristics.
Participants generally agree that the spectral characteristics do not change with crystal size, but there is disagreement regarding the impact on lasing power and the potential effect on lifetime, indicating that multiple competing views remain.
The discussion includes references to external threads that may contain additional information or differing opinions, but the relevance and clarity of those discussions are questioned by some participants.

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