Thanks for that little piece of info. I'm getting my goggles tommorow from optotronics and ill see if its modehopping. What would be the difference in power with a perfect tem00 and a near perfect tem00?Chad said:Keep in mind that there's a difference between mode hopping and running in a mode that isn't TEM[sub]00[/sub]. If it's just an oval shaped dot, it's probably what some companies call "Near TEM[sub]00[/sub]" - something that could be classified as either TEM[sub]00[/sub] or TEM[sub]01[/sub].
Get some goggles, defocus the unit, and shine it at a black target... if you can see 2 dots, it's TEM[sub]01[/sub].
Thats great to hear Would of been really bad if it was. If I RMA it the new one probably wouldnt get to Australia fast enough.Murudai said:Nah freshert, that doesn't look mode hopped to me.
The oval might be a side effect of the fact that the laser is focusable, who knows :-? Or probably just near-TEM00 like Chad said.
Modehopping only affects DPSS lasers (I think). It's when the dot is not one dot. Like a dot becomes two dots instead of one. For a better explanation ask one of the pros :-[laze_doctor said:What exactly does modehopping refer to? I tried googling it, but no luck.
