Default could this be the MOST MODIFIABLE 532nm handheld???FGB rayfoss

hello boys.... i noticed that the bost cheap and powerfull laser chat 215 dollars can buy.... is the rayfoss fgb 200mw

www.rayfoss.com

the laser i think is good.. but i am not sure about beam specs. in the site i read 1.7mrad..... i hope it could be better.
and i am thinking about the ease of opening it. ........and CHANDE the mA output of the driver.. to have MORE mw.......... i don't kow if it is possible. it should have a 2watt diode.... but this could be an "unlucky unit " of the big brother 350mw...... with most efficient crystals.


if the quality is the same.. it can be tuned UP until 300... 350mw.... but if it is a pretested____low efficiency module.... it is just setted at the max power

.... if some member can test( member with more tech skills or veterans.....) it.....and say that it can easyly tuned up untill 350mw stable...... at 215$ it could be the MOST IMPORTANT BEST BUY for all us.

I personally wouldn't risk $215 for a pot mod! It could be a high efficiency 1W module couldn't it?! In which case you'd get no light fast. Rayfoss have had good reviews in the past, (but also not so good), so you are trusting them a lot to assume it is going to output 200mW in the first place. 650mA current seems a little low to me to get 200mW but maybe they're clues that others interpret as a good sign.

Best thing to do first would be to check the current draw yourself to get any clues as to output of the driver. But you'd have to buy one first to test this. Please let us know how the tests go.

Never know. I have plans to get the 600mw with some special needs to get it cheap, but they told me they use a 2W IR laser for their 600mW laser. Doesn't this mean it can be a 2W laser actually? It sounds like they use high power IR lasers tuned way down for a long life. I'll be able to tap into the circuits before installing it to my own host, but rather not pot mod it still

a 2W IR diode will not produce 2W of green. most of the power is lost in the conversion.

Very true, isn't the most green you can hope to get for 1W of 808nm is about
200~250mW of 532nm. I know the coversion is some where around there...

Well, rayfoss told me (note their laser says >600mW) they usually set them and meter them between 650-700+mw. It's just guaranteed a 600mw or more.

Note to anyone looking to buy this laser, they had to change the host due to complaints. It looks exactly the same, but the body is all black, and the switch is silver in the picture I received. When I get it in the mail, I will do a review ASAP.

Efficiency from 808 to 532 is typically around 20-25% but can be as high as ~30% in a good setup.

In most cheap greens, they run the pump at full capacity to get the most "bang for the buck" factor which is what they rely on for sales.
I would guess that the laser in question is no different from the other cheap greens. You will be lucky if it outputs the rated power of 200mW. Asking for >300mW is just absurd.

This laser is not worth a gamble if you ask me. I will never buy "high power" DPSS from a knock-off reseller.
The cheap China companies have their niche in the hobby. They are good for cheap low power pens and that is about it. For anything >100mW, I would rather spend my money on something that I know will deliver the rated power as a minimum so I don't have to worry about modifying it so it will actually live up to specs.

And the <1.7mRad divergence figure is a huge turn-off.

Faona informed me just today that the pump is ran at 80% capacity, and that the 275mW average, 315 peak tested is for my specific laser. So far, I am very pleased. However, if I get the battery, and the laser is sh*t, then my feelings will change. I really doubt that's going to happen, though. Faona has been incredibly helpful, and seemingly honest with me. I'm very excited to pop a battery into this sucker.

BTW, received the laser yesterday. My only negative comment is that the threads on the front cap don't line up very well, and unless you apply slight pressure, it ends up a little crooked. This is pretty easily corrected, though. And, unlike the Arctic, the inside of this thing isn't coated in thermal paste.
When I get the battery, I'll do a full review. After I learn how to post a new thread.
