Hey everyone. Today I wanted to try to build a 473nm laser using parts from B&W tek laser, which was rated 10mW. Tried to look Sams Laser FAQ, but couldn’t find anything about my case. I replaced an old 1.5W 808nm pump with 3W one, with FAC lens. The problems started happening when I tried to...

I had business with them multiple times, quality is nice, talking about their modules and pointers.

I get stable 1400mw. I’m not sure about those crystals, I opened this laser for 10 seconds just to take photos. I really like how it’s made. Never seen light goes 30° out of crystal. Also: diode is up side down. If those crystals are hydroscopic, was it okay for laser to be open, under standard...

Intresting beam path here, after YVO is significant angle to lens and KTP.

They should think about efficiency, 2W in and 40mw out is a lot.

Nope, he said they didn’t produce enough of them to start selling. This was last time I contacted him on 30th August. The one thing I don’t like in these units is small crystal. Being 1x1x1.5mm it’s very hard to work with. I suggested them to increase the size. Will the power increase with size...

It’s been Ok to me this morning. Now it comes like this, lol. Maybe this happened because I’m in Turkey now, network stuff I got it solved: Now it came back normal again.

Greetings, Miya. Have a nice time being here :) 405nm beams are beautiful ones. Sadly my BRD-209 died.

What happened to them again. https://www.sanwulasers.com Some sort of a joke I guess.

Man... isn’t that host too small for such diode at that current? What duty cycle it has?

I ran it for 10 minutes and had no issues. I does not get even warm. But since IR diode working temperature being 15-30°C, I think anything around that will do.

I run my 800mw 532nm ple pro for 5 mins and get 300-400mw. Power is dropping dramatically after long run. Also you can’t expect more than 300-400mw if weather is cold. My unit is super unstable. But it’s kicking at room temp. Peaks 1200 easily.

Hey, nice to see you back. I would personally prefer 462 because of more beam visibility , due to shorter WL than 520. I have J/L 532nm 800mw and it peaks around 1200. Jetlasers are super responsible about their stuff.

As an Overwatch player, I was also thinking lasers could be used to bring those guns in real life. Having no proper equipment makes difficult to make one of these.

I think Aussie is just selling his leftovers from previous batch.

Are you interested in 565? It will be great addition to your collection. I’ve sent a question to them regarding 565.

20-30mW. I talked to him on alibaba. I’m not sure about 565’s yet. Gotta ask. I’d love to own one of 565’s.

I’m in for 4 or 5. Hehe. Who can host a GB?

They are 30 each if bought one by one.

He sent me email this morning, I guess you all can now email Freeman also.
