Well, I was really bored today. Earlier I had my 650nm sitting around so I decided to quick review that one, and then I looked at my pile of handhelds and realized there was one that didn't get reviewed yet.
I bought this off eytyxhs in his FS thread two months ago for around $200, and this is one of the most stable of its kind that I've heard of. Of course I wanted it :na:
Apparently the paint was chipping off of his, so he sent it over to lazereer to have it polished.
Well, polishes don't last forever unfortunately
Good news is, I talked to lazereer about it by chance and he said he'd repolish it for me since he had already done it to this specific laser. Just goes to show how awesome Angelos is. This is what it looked like before it got ugly again.
It's also rock solid stable once its warm, it even gets hot, but it can easily be left on for a minute without any power decline.
Why? I would imagine that the 808nm diode starts out at a slightly lower wavelength, heats up and actually hits 808nm (the peak absorbtion, its much more efficient than even 807nm is) Nd:YVO4 is a little picky about temp, but not in the range this operates at. KTP then doubles it, and KTP likes to be run warm... so, I think its just luck of the draw that makes this one so good
Turned it on, of course batteries were dead.
It runs on AAA's, so at least they're somewhat readily available. Or not, I just jacked the TV remote's. At least these work right
I decided to go outside since the dryer was running, decent amount of fog being spat out the wall for some shots.
As for color, I think this picture is about as accurate as ever comparing 589nm to 593.5nm (at least on my monitors and device screens)
Aaaand crap, batteries from the remote died. Well, good enough.
Oh, also, when it's too cold or the batteries are dead, you can see the 532nm emission! (It also does 671nm, but only when the yellow is lasing)
:thanks: for reading guys!
