Jetlasers Green Laser IR Filter Question (Solved! 1.2W peak of green!)

Hi,

I just received a 600mW PL-C Jetlasers 532nm laser. (review later) Turned it on and it is BRIGHT, but now I have a question, when I asked Gray if the 600mW was after IR Filtering and he told me that yes, the output was AFTER IR firtering.

Quote from Gray:
...and yes, they're of course after the ir filtering...

So, I tested the laser on my LPM and the results were a little disturbing, average of 930mW and over 1W of peak. So I think I can conclude that the laser DON'T have a IR Filter. :) But how do I know for sure? Where I can easily get a IR filter? (I'm not in US).

Thanks

Re: Jetlasers Green Laser IR Filter Question

if it IS IR filtered I would not be 'disturbed' !!!

AFAIK all the PL-C 532s DPSS are filtered.

Re: Jetlasers Green Laser IR Filter Question

Well DNJY, I tried your suggested methods, the look at the dot one and trought the googles (I tested 3 different googles) the dot doesn't have any different color and trought the googles I get 0mW on the LPM.

if it IS IR filtered I would not be 'disturbed' !!!

hakzaw1, yep, maybe "disturbed" is not the right word. :)

Well, I charged one AW battery and look at the peak (average 890-950mW)

Re: Jetlasers Green Laser IR Filter Question

Ok, I forgot my 473nm has an IR filter that can be removed, so I removed it and glued the front of the 473nm (with IR Filter) on the 532nm and aligned it with the beam, and the results on the LPM still the same. :p

Wow. :eek:
I'm still scratching my head trying to figure out how that would happen.
Assuming a 2.5W pump diode that's 50% efficiency. There has to be something going on here...

I might need to get a bigger green now.

any mode hopping?

Gray wrote me that this can happen as the powers go up-- total disclosure- honest guy that Gray!!!

with the GB price that comes out to a peak price of about 50 cents per mW

Well, CNI is now selling a 1W 532nm that they told me some overspec units goes over 1.2W stable. Of course it costs over twice this one I got from jetlasers.

any mode hopping?

Well, I really didn't see any, will look for it later.
I did read about mode hopping here: http://laserpointerforums.com/f44/some-facts-about-mode-hopping-28456.html and the dot is near TEM00.

Cheers

OMFG 1.2W peak???? :eek: that's the world's most powerful green handheld afaik :beer:

I agree, something is not right, it's not possible with current technology using a 2.5W diode. 1.2W of 532nm will burn through several layers of black electrical tape stacked pretty much instantly. Does this happen with this laser.
It could be the meter is no longer in calibration. I've seen this kind of thing happen with a silicon sensor or thermal sensor that has had too high of beam density applied. A 3 or 5 watt meter means that you can apply 3-5 Watts as long as the beam density is does not exceed that in the spec. I've seem a 3W thermal sensor get ruined by only 350mW when the spot size of the 350mW is only 1mm in diameter. After that, the sensor will read very high as the thermal surface has been fried.
I just looked back through customer support emails and found that this happened with a RPL, a person bought an RPL-400 about 18 months ago and when he got it, he emailed in great excitement that it was measuring on his thermal meter at over 900mW. I told him it wasn't possible and after some trouble shooting it was found his meter was giving him false results at high output levels, it worked fine for his other lasers of 200mw and less.
To help you try and figure this out, try lighting various things on fire and tell us what you find. For instance 1.2W 532nm should instantly light a match from 25-30ft, (even farther if the beam is focusable).

Want one like she got???
Gb#2 jetlasers IS NOW ON>PM Gray w/request

US and Canadian buyers- contact Gray(@JETLASERS) for the GB #2 (part 2) price on these-- IIRC I think they are 660$ plus $33 total for all shipping.

PM your price quote to me and I will add you to the list for GB#2.

It has a limit of 13 lasers.

ATM there are iirc 3 on the list now-
Two for arythna and one for AquariusLaser

You can request metering by Gray.

@Bootleg- her meter is brand new

OMG 1.2Watt green ? That laser is brighter than the 445 1.2W laser.
You are very lucky !
