Do higher-powered lasers have lower beam qualities in general?
When NOVAlasers released the "X-150" and "X-175" lasers, it could no longer guarantee a TEM[sub]00[/sub] beam. I've also noticed that high-powered lab lasers also have worse specs than low-powered ones.
Also, I've noticed that Optotronics' lab lasers (which currently go up to 500 mW) have pretty good specs (1.5 mm at 1 mrad), while the multi-Watt systems from LaserGlow have not-so-good specs (3 mm at 2 mrad). The higher-powered lasers also have a near-TEM[sub]00[/sub] beam instead of a true TEM[sub]00[/sub] one.
Is it hard to get good beam qualities on high-powered lasers?
(By the way, it'd be nice Optotronics would start selling those high-powered multi-Watt lasers like LaserGlow does. That would be totally sweet!)
