ThorFire C8S 1.5W 405nm

Nice new addition to your collection!
Have you you actually LPM'ed your output at 1.5W, you are usually very lucky to get over 1Watt from these?

Thanks Bowtie,
well , no, unfortunately I do not have a LPM, however, from tests carried out on cd black punctures more quickly than 1W !!!! and anyway in Italy there is !!!! as soon as I can I will buy from Jordan but a lot of attention to the customs !

It could be 3w you never know.

Nice. If this is a 3watt 405 it would be a burner for sure. :gj:

Very nice! However I doubt it is in fact 1.5W.
If you seriously overdrive them then it is possible in rare cases, but again unlikely.
Without a calibrated LPM you can't be 100% sure.
Also these are impressive single mode lasers and I have found they burn just as well as those 2W M140's even at <1W powers.
Anyway good laser to have in your collection. :beer:

I've been following reports regarding the 900 mw 405 nm laser pointers which use the "16 X" BDR-209 burner diode and they usually die an early death, need to be throttled back to about 700 mw output for a longer life. They are becoming less expensive though, not such a big deal, just replace when they burn out: https://sites.google.com/site/dtrlpf/home/diodes/bdr-209-405nm-16x-diodes

The reason those diodes might appear to be producing far more burning power is because they are single mode with a very tiny emitter at such a short wavelength, due to these two properties, when collimated with a fairly small diameter lens, the output can go a relatively long distance without diverging much, as well as the ability to focus them down to a far smaller spot to produce a higher power density than many higher wattage multimode diodes which have far larger emitter dyes.

Caution, that diode is wicked dangerous due to distance it can go before it expands much, ability to focus to a small spot at distance, that and the wavelength being near UV as well as appearing fairly weak when it isn't.

I would not want to get hit in the eye by any laser, but especially not that one. Being near-UV don't look at the spot up close or several feet away for that matter either, this is good advice for any laser spot of much power, but particularly 405 nm, that wavelength is not at all biologically friendly, a very high energy wavelength compared to others in the vis spectrum. This is a nasty wavelength for a laser pointer, see more here:

OK, did my part, you've been warned.

Yep , Could be above 1.5 W, and may be under ... this I unfortunately do not I know ! I have to be the one that says the seller , even if, however, a certain difference the note ! I, for example, to see if a laser is really what it says it is , point "the beam" in the shape of a point at a certain distance in the middle of the palm of my hand , if I notice that immediately pinches then it means that maybe it is actually that wattage ...if, instead, the pinch only after a few seconds ...then it means that it is not what it claims to be ! it would be my policy of "LPM"! not having it just so I can test them ! Anyway, these lasers from 405nm in fact I have already stewed ! mainly because of the hazards of UV, tending to violet ! Now I'll stop with the construction ! so I don't have neither the host nor laser complete ! Now I'll work on the build host such as the ones that makes Lifetime17 , of course I will try , as I tried with the laserpointer ! The health first of all !

I wish I knew what diode was in it, I know of no other higher output diode than the BDR-209 at that wavelength and it will pinch or sting you in a quick half a second, doesn't take much time due to the tiny little beam spot and high energy wavelength.

Most certainly not over 1.5W. 1.2W at a max is more likely. Although don't be disheartened if it is actually 900-950mW. 1.5W+ is unreasonable for a BDR-209 without seriously overdriving to the point of current damage.
Pointing the laser at the palm of your hand is not a way of measuring lasers.
Also single modes like Alaskan pointed out have a higher power density due to the guassian profile of the beam.

Edit: It definitely would be a BDR-209 Alaskan.

I could be that much power, but a rare BDR-209 to be able to be pushed that hard, if true. They are failing fast enough when pushing close to 900 mw as it is. My suspicion is it is not really producing that much power, I don't believe that diode can do that much but I suppose, out of a huge number of them, maybe some can? Doubtful though.

Anyway, this morning when I opened (the module 12x45mm) I saw on the back of the diode soldered to the driver , I found the symbol of the Nichia engraved on the diode in the back !

Nichia? 1W+ 405nm. :thinking:

Here's a DTR thread showing he was able to get 1.25 watts out of one of those BDR-209 diodes: http://laserpointerforums.com/f38/pioneer-16x-bdr-209dbk-88124.html

Yes, you're absolutely right Alaskan !
In fact, Curtis even astonishes me !

Sorry Alaskan , well , and Jordan did not get to 1.2 W ? This is not anyway to push ?

I'm not saying don't own one, just treat it with extra caution.
