Hello! Welcome to LPF! :yh: Nice laser you have! I wish to have a 1W blue handheld too. I use the Dropbox + img tag, so my images never expires. Unfortunately I'm from Brazil, not close to you. :beer:

I think 30s for warm up is fine, since is a true high power laser, not all DPSS lasers are the same, I had one 303 that mode hops frequently during warm up, and one that never did this, if after 30s the beam is stable, I think there's no problem. Just search a bit more what is mode hopping, you...

Hey! Welcome to LPF! :yh: I ever wondered how is to live in a place like Alaska, full of snow and cold winds, because of this, all my wallpapers have some kind of snow in it, I just get amazed seeing all the forests and how peacefully it looks.

I'm glad this helped! :yh:

Good choice with the Sci-Fi laser, is a shop from a member of LPF, so you will help our community too. :yh: Agree! Sometimes buy the parts becomes more expensive than the thing assembled, even with the 301 ones!

That's true, all DPSS lasers suffer from this, since they are way more complicated than direct diode ones. LaserBTB/Skylasers is a good start, but Sci-Fi lasers are well recommended too. About it being durable, almost all the reviews I saw said that are quality products. There's a plenty of...

I had one laser that need up to 2 minutes on to reach full power, that's because of another characteristic of DPSS lasers: mode hopping. It is very complicated but interesting, happens when the crystals expands during warm up time, the beam changes shapes and the output power suffer from big...

Probably is mode hoping, what is normal, learn more about DPSS lasers and you will find out why this happens. Is this a focusable laser or a fixed focus one?

Not easy, those are unbranded lasers that are manufactured massively. If you want real power, I can't recommend anything. Most advertised as "burn matches" or "burning lasers" are just like the ones that you and I bought. Looking at SkyLasers store on Aliexpress, you can have a idea (yes, you...

Is normal to these lasers have bad divergence, did you measured it? You can find here in the forum how to proceed. At 370mA there's no way to be a true 200mW laser, seems like 50~75mW (most Chinese lasers are in this power range, IR+Green).

I bought a 200mW laser from Aliexpress that burns black things, and burn my skin, this doesn't tell that there's no IR coming from it. Can you provide some more info? Like focus range, beam diameter, beam divergence and input current? I'll like to compare with my laser from Aliexpress. I can't...

From the images, seems that your spring is just soldered, it means that if you melt the solder it must come off easily. By the way, if it doesn't come off, then there's a hole in the board where part of the spring is inserted, if this is your case, you need to melt the solder and with some tool...

Shared it on FB, this made me very sad, I hope she gets well soon (I know a burned eye is irreparable :( ) and the owner of the laser gets punished!

Welcome to LPF! :yh:

I agree with you. Let's wait some more info from outsider.

That said, at 5mW I think isn't deep red, but almost invisible.

780nm are found in CD-R burners, but are infrared and 150mW+

You can try some 12mm modules, first measure the size of the module that came with your laser and search for one with the same dimensions. For this you will need to disassemble it, if you need help let us know! :beer: Good luck! :yh:

I need to know what more the members wanna see, I'll try to provide those information soon as I can. Thanks for the input! :yh: ------- EDIT ------- Added to the first page.

I had some click buton lasers, one was a green JD-850 (that arrived broken) and one is a purple GD-320 (for my mother), I need to get used to it, if not it can be very dangerous. Comparing the output to the other green lasers I had, this is the brighter one. It doesn't burn too well, but the...
