im looking for a 575/571nm lasence module if anyone has one they want to sell. I don’t really care how much power it outputs as long as it works. thanks!
 





Me too. Bring out your yellows and turn them into gas money
 
PM me with a price, I have one left.
If the price is right, I will think about it.
 
I have a working 571nm lasence module with TTL driver/fan, but I love it and money doesn't entice me much anymore. However, I enjoy trades, and I'm highly interested in the 580nm to 627nm region of your laser list. I'm not a laser power monger, but I am a bit mode snobby.

The camera and your screen only has RGB so it looks more green in images. To your eye its a green-yellow look. Will do over 30mW steady, haven't tried getting more power, its operated turned down to 0.5mW output after a few days of getting it, and its never been opened or disassembled.

I'm also happy to kick-in cash with the trade to compensate for whatever value difference may exist to make the trade fair to you, I only like to do things where both sides end up happy. :-)

Hmm, I have this 5mw CNI GLP 589nm pen, i have realigned the crystals as it was misaligned some time ago and it works well in TEM00 I don’t know how much power it is outputting now but it looks to be 3-5mw, also it is dim for the first 10 seconds when you turn it on but once it heats up, it works fine, would this be a fair trade?


i would like to know something though, is the power of the module at 0.5mw right now or is it at 30-50mw because it could mean crystal problems if it is that dim. Is there any way you can try to increase the power without disassembling it?
 
The finicky 589nm pen pen is a fair trade to me. Stoked to finally have a 589nm.

It's definitely low power because I turned the trim pot all the way down, but my laser power meter only goes to 30mW to be able to validate it higher than that for you. It was sold as a claimed "50mW" but I can't confirm that number and I personally used it for low power. I can send a picture tomorrow of it pegging out my LPM at +30mW.
 
ok, I’ll send some pictures of the 589nm pen, if you align the Crystals right, you can get some higher powers (10-15mw) out of it ( not in TEM00) and with maybe a bit of fiddling around with it, you might be able to Get 10mw in TEM00!
 
I love a TEM00 beam, but reaching 10mW isn't important to me, even 2mW is plenty. Can I confirm it will lase without me taking it apart and aligning crystals? (even if it takes 10sec to reach full power).
 
Yes, it will lase without you taking it apart, it just takes a while to warm up. Also, the laser has Some small scratches on the
outside of the housing
 
Thats with the sensor about 15mm above the output lens. The multiplier for this wavelength is about 1.2x, or ~42mW

In this shot its just sitting on the output face and will peg-out my 40mW meter (*1.2 = 47mW) 47mW is as hard as its ever been driven, and may output higher but I would need a better LPM to quantify it and don't want to risk damage.

Can you share an image of the 589nm beam?

i will once I get home later today, how do I power the 571nm laser?
 
I powered it from an power supply to be able to measure and adjust current easily. You can also power it from its own laser and fan driver board, but it will max current around 1.5Amps, and it wants to see ~3.1Amps to peg out my watt meter.
