O-LIKE 600mW green IR filtered laser

Hi,

I came over this laser: 600mW Portable green laser IR filtered£­>250~500mw Portable green laser£­>Laser&lighting products£­>www.0-like.com

The cost is 800 dollars. I know that thr price for other lasers rated at this power is much higher.

Is this a real deal, or it it bad filter? It says 2W driver diode, with 2A current draw. So 600mW green output sounds reasonable...

I'd say it's probably a great deal. Most of what o-like sells is.

Beam divergence is big though. I'd rather pay what 960 at CNI for a tighter beam and more peace of mind. Jayrob did make a review about o-likes tho

You won't get a 600mW green at CNI for $960 though

2mRad divergence really isn't much worse than you get at CNI, because CNI has such low beam diameters the divergence on these units is pretty high. Even if they claim 1.2mRad, I think it is pretty rare to come across a CNI handheld under 1.5mRad (from what others have posted). I think my 178mW CNI pen is around 1.7mRad IIRC, this is easily acceptable IMO. Also, I don't you can get a 600mW greenie from CNI for $960.

Hi Rob,
You won't get a 600mw portable from CNI or anyone else for that matter, they just don't exist.
Perhaps there is one that can peak at 600mw for a second or two when the conditions are just right and includes some IR in that number as well. Right now, a 600mw portable laser is for someone who doesn't have the capability to measure laser power or doesn't know what 600mw really looks like. As for divergence, nothing over 1.5mrad is acceptable if you want the beam to have burning power at distance, even 1.5mrad is pretty pitiful. There's a hugh difference between 1.2 and 1.5mrad, it's not just a small number of 0.3 difference. It's an angular measurement and even 0.1mrad will make a big difference in spot size, burning power and maximum distance as the distance increases.
Ask lots of questions before buying a supposed "600mw portable" such as
1. beam diameter
2. TEM mode
3. run time / duty cycle
4. amount of IR included in their rating, just because it has an "IR filter" doesn't mean it blocks all IR.
5. If the rated output is peak or average and if it's average, over what length of time is it averaged.
6. Divergence
7. If they promise it will meet promised spec and replace if needed.
8. Warranty period

You might be amazed at the answers you get, I have been.
Often they won't even reply to you when you ask these kinds of questions as they know you know what you want and will verify the product's performance.

Just ask those qestions and make an informed purchase, not one that's based solely on an undefined output power number.

I was just going from Ohada's review don't know if you guys have seen it

Edit button doesn't work for me I'm sorry phone is screwy.

But there is one member that has a hercules that peaks at 800mw or something and is stable at something like 710mw. Unlimited duty cycle and correctly measured by laserglow
