Recently found out 593nm lasers are cheap for some reason. Only one I could find though was sanwu pocket and I wanted one in a pen style. Checked alibaba and nothing, ended up finding one on ebay, but surely that's not the only option? I saw sanwu has a 555nm laser too I want to try but again, I...

Also willing to trade for a Laserglow Aquarius 473nm 3mW or anything else (other than SANWU RGB) in my signature. PM me

Did not expect to find this. https://www.walmart.com/browse/laserglow-technologies/YnJhbmQ6TGFzZXJnbG93IFRlY2hub2xvZ2llcwieie Obviously it's a reseller, but why? And why Walmart?

Found this in a facebook add https://kaoroo.com/products/laser-torch?variant=31851745673264 The green seems pretty powerful too. I ordered one of each color so see how powerful they are. I assume it's a 1W Blue which makes it the cheapest I have ever seen. Hell, the diode costs more than...

Just got one off ebay for $110 not a bad deal I don't think. They have no idea how powerful it is, only that it's probably more powerful than a 20mW laser they sold once. If it's less than 75mW I'm going to try to pot mod it to see if I can get it to 100-150mW and if that fails, I want to...

If you have one your willing to part with send me a pm!

I would like the following builds BDR 16X 405nm 800-900mW Sharp 505nm 50-75mW PL520 75-100mW I can buy the module from dtr and have it shipped to you, or you can just aquire all the parts on your own. I would like reverse polarity protection on all lasers. And enough heatsinking for a run...

They changed their 589nm options, and were out of stock of a bunch of things, now the laser pointer section shows "page not found". If this is true that would be really unfortunate. They had really nice lasers particularly 589nm and their GLP 532nm pointers. Also other than laserglow which is...

What is the minimum output for each color? Could I do 5mW for each diode? What is the divergence of each diode? What is the divergence as a whole? What do the vials do? Is the basic plan worth it? Thanks

For Sale Ophir 20C-A-1-Y Laser Power Meter Includes everything you see above. Can read from 1mW to 5000mW standalone or with datalogging via the laserbee software (included). Can read over 15000mW if you install a heatsink (cost's less than $10). Response time 0-95% 1 second faster than...

Hi, I just purchased an Ophir LPM from off-road freak but I am noticing it reads about 5-10% higher than my LPM from Astralist. Anyone in the US with a trusted LPM able to measure a laser and send it to me so I can compare it? I can give a trusted third party the money equal to the value of...

Hi, Just ordered the 532nm 800mW PL-E pro, I didn't see a duty cycle listed. Does anyone know what it is? I saw one guy say it was unlimited but I'm not sure about that.

This forum used to have a lot more activity, tons of people selling stuff in the BST section, and all sorts of discussions. It seems to be very little activity now. Anyone else noticed this? I only pop in every once in awhile so I'm not sure if this is a recent thing or a gradual decline...

I have read in many places that an Ophir 20C can read up to 5W and 10-20W heatsinked. Any idea where to get a heatsink or would someone be able to make one? How much would it cost? Would it just need a hunk of metal or a cooling fan as well? Thanks :yh:

Hi, I purchased this to make my own LPM but I never got around to it and I didn't want to risk damaging it. It's in very good condition. Sensor: $350 Shipping: Free (CONUS) Intl Shipping: PM me Also thinking about selling my 900mW 520nm. Make me an offer.

Which 520nm (or 515nm) diode has the best divergence? I don't care about the power. Are dpss 532nm lasers still better? What's the best divergence diodes available in any wavelength? I read about the lpc-826 is that still the best? I want to build a laser, and I want the divergence to be the...
