I have been looking at green lasers recently and I am looking for a 150mW pointer and I came across the one on Rayfoss.
http://www.rayfoss.com/pro_info.asp?id=1473(Like the look)

I e-mailed him to ask about power and got back this

"Hello,Thanks for your inquiry!

The average power out put is 135mW without IR device. We are serching suitable IR leanse for this laser torch now...once found we plan to install IR to our laser torch design ...But now it is without IR filter...

Any comments please kindly let us know!"

The O-Like on the other hand http://www.o-like.com/b2b_cpinfo.asp?id=930
If this is like her modules it should put out ~140mW? and peak at ~170mW?

I just want to know what you think about the Rayfoss and if it is worth it. Thanks!

Im not sure about rayfoss, but i know for sure that you wont be disappointed with o-like, you will get your advertised power and more. Oh yeah i bet it would peak at 170mW if not more, if its not up to spec you can get a replacement from susie. That is a good price for the rayfoss though.

I think the rayfoss may be better, just because it uses CR123a, I'd think it's more possible it would be in the >100mW regions. I always thought you can't go too high with just AAA batteries because it can't draw enough power to run in the hundreds of mWs regions, but someone can easily correct me if I'm wrong.

Well, it doesn't really matter on what batteries you use as long as you meet the 3v requirement for the driver/diode, you won't have as long as a battery life with the AAA's but that's all. You might have more power with the cr123 as it peaks at 4.2v if the driver is one of those Voltage ramp up drivers.

Well I think i might go with the Rayfoss because of the batteries and the host.

If you do, please write up a review on the product you purchased so we can get to know this new site! :)

It might take some time to get the funds but I will do the best i can without a LPM. Thank you!

I've been mailing with rayfoss about this one: Rayfoss

They say to guarantee at least 170 mW. Also, they reckon it would keep up at 170 mW for a minute of on time, but that part doesnt seem to be guaranteed. For $145 it sounds pretty tempting.

Well, this one looks great, too. But what about beam divergence?
Click to expand...

Yes, beam divergence...a little increase means alot less burning power as it's an exponential number. The spec on the rayfoss was 1.5 to 2.5mrad, so assuming it is at the best end of this range and 1.5mrad, that equates to the beam spreading out (and loss of burning power over distance) at a rate of ~ 55% faster than a laser with a divergence of 1.2mrad.
Here's a link on our site with a plot of this.

Curiously, they list two figures:

Spot Diameters at 10 meter: <18mm
Beam Radiation Angle: 1.5-2.5mrad

I am unsure how wide the beam from the aperture is, but say it would be 2 mm wide. The 18mm at 10 meters then equates to ~1.6 mrad... but it also depends on how you define the spot diameter. That might seem trivial, but there is a pretty big difference in what appears to your eye, and the size the spot is when you define the border of it at 50% brightness of the middle.

If its defined at what it looks like to the eye (i.e. the border is 1% or 5% of the middle brightness or so), 18mm at 10m is a pretty good figure. If thats the limit of 50% power and the distribution is more gaussian, it would be dissapointing.

As for burning power goes: i'd suggest getting a focussable laser for that really.

This one is focusable ....

200mw Green

and it uses the more powerful #18650 battery.

The search also shows a 100mw focusable green ...

100mw Green

I have ordered one for lens assembly power increase testing.

Given the two choices. I would go with the Rayfoss one, simply because of the waterproof host:
