I am not seeing this one on their site (PGL-III-C-532-100mW/Unit USD120.000
Also does it take 2 "C" batteries or a 18650? One more question is it rock stable? I have a few 532's and the only stable one is a cheap pen at 65mW. I know dpss but I really want a stable 100mW pointer.
If the price is right would be a bit vague , for a 589nn that has a beam that'll be comparable to that of a 532 at 100mW ,you'll need almost 1.3 times the power after taking into the account of Rayleigh scattering.
So you'll probably end up buying a 50mW +
That's gonna cost ya at round $500 .
Each laser acts differently but I can talk based on my 589, it sometimes but rarely starts TEM01 ()(), give it a few seconds to warm up and then its a circle, TEM00 where it usually starts, give it a minute or so and its back to TEM01 and by then you should let it cool down.
I don't personally own one so I can't comment on how "often does mode hopping" happen for a 589 dpss.
But I CAN help with the price.
The more getting into a GB, the cheaper it gets.
Thats from the last GB.
If you got friends , and you wonder if they wanna get into lasers. This is a great time to start.
