Hello,

Im looking for a new handled green laser, i already own a blue one (1w) but i heard that green beam is much more glowy.

So i looked on the topic "LASER Bible" and i found laserpointerpro.com website. Im very confuse about the price of green handled laser :

1000mW 532nm High-power Green Laser Pointer : $287,99

In my opinion it's very cheap, so i think this website is not reliable. warnlaser.com sell 1w green laser for $1399 !!

I dont want to burn things, just "need" a better beam than my blue laser.

Could you please give me some advice ?

By the way english is not my main langage, sorry for all my mistakes.

They look just fine !

Do you think the 500Mw green beam is more visible than a 1000mw blue beam ?

Thanks a lot !

WAY brighter :beer: A 1000mW 445nm (blue) laser doesn't make the greatest beam, because it's away from the 532nm (green).

Yes. Even a 200mW green laser can appear as bright as a 1000mW blue. A 100mW green is plenty bright. All of these strengths can blind you. you'll want safety glasses to protect your eyes.

Which one do you think is the brighter, between those two :

1000mW 532nm High-power Green Laser Pointer : 575.98 ; $287.99 Save 50%

LZCR - 532nm 500mW High Power DPSS Green Laser Pointer : $319.99

Excuse me to disturb you all, but i want to make a good choice !

search around the forum a bit.
You will find this link in plenty of threads that will answer your question: :)
532nm 1000 vs 532nm 500mw comparison beam

Brightness is effected by 2 factors. Output power, and wavelength.
A Beam will appear brighter no matter what with more output power (mw), however wavelength is an entire different story.
Refer to something like this for sensitivity:

You said your 1 watt is 445, not positve so correct me if im wrong, but im pretty sure your going to need a different set of goggles for a 532nm, I think the goggles you have probably only work for 445 and 405nm (blu ray) laser protection.

I have a set of cheapy goggles that work well for for both my 1w 445, and my 532. but then again the 532 I have is only 50mw :(

either way, they probably go up to around 540nm, I see that being a common label
