The size of a neodymium doped yttrium aluminum garnet (Nd:YAG) laser crystal rod significantly influences the lasing power output but does not alter the spectral characteristics of the laser. A comparison between a 4-by-7 mm Nd:YAG rod and a 20-by-35 mm Nd:YAG rod reveals that larger crystals can produce greater lasing power. However, concerns regarding the impact of crystal size on the laser's lifetime were raised, indicating that further investigation is warranted. The discussion emphasizes the importance of focusing on relevant factors rather than unrelated topics such as radioactive decay.

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.
