Is this green laser good?

I think the people who made the spec are just a plain of noob.

Also the shopkeeper at the retailer shop herself says that the 200mW one can burn.

it might burn but that doesn't mean it is 200mW, not to mention half the output could be IR and it might burn up close. If it is a shop ask to compare your laser to the new one.

If they are noobs making the specs, what makes you think they aren't noobs making the laser? I have a very strong suspicion that all of those newwish style pointers are exactly the same.

And not to be mean or anything, but of course she is going to say it burns, she wants you to buy it!

Even 50mW will burn if it is focused correctly, though those pens are most likely not, and have horrible divergence. It may burn, and it may be bright, but it is NOT 200mW. If its only a few bucks then go for it, but if its more that $40 and thats pushing it, then just look elsewhere...

Lolx,you may be right.:yh:
Now it makes me want to think again whether want to buy those laser or not.:thinking:

Can someone give me link to a 'true' 200mW green laser spec for me to compare with this green laser spec?

Portable laser, 532 nm green, 473 nm blue, red, yellow, infrared handheld laser.
Green Laser Pointer ----- 532nm Laser ----- Viper Series Lasers :: Handheld Lasers :: Dragon Lasers
Green Handheld Laser --- 532nm Laser ----- Spartan Series Lasers :: Handheld Lasers :: Dragon Lasers
As I said earlier, be ready to spend several hundred to get a real 200mW greenie...

 

[Pontiacg5]

But if you spend the cash now, you won't regret it

125mW of pure nicely culminated green is a sight to see!

 

[Grix]

The highest I've heard of is 523nm.

I don't think that there are 532nm diodes, and for that matter I don't think anybody could buy a green diode. IIRC they are still at the experimental stage.

Just fyi, the greenest diode available is 531nm, there was a major breakthrough in green diode technology a while ago.

 

[Pontiacg5]

Thats what I thought, I don't think there is a 532nm diode but there are diodes around that wavelength.

Can you even buy a green diode at the moment? I haven't seen a spec sheet or price sheet with a green diode on there yet. I think its still in a research stage and they are not being mass produced yet.
