i have a 405nm phr-803T blu ray diode, and a simple JR. dorcy flashlight. Would i be able to use the circuit board that comes with the flashlight or would i need to make a different one?

Ok so my 405nm Diode is driven at 110mA and is focused to a tiny dot, it burnt yesterday, but now it seemed to get dim and won't burn at all. The laser is being powered by 8 AA batteries, I measured the voltage while use and it was around 10-11 (it's supposed to be 12) the mA draw was still at 110, I do remember dropping the assembly from about 2 feet today, but I checked the laser diode window and it didn't seem to be broken (the window on the actual diode, not the lens in the Aixiz module)
Do you even know what a tactical laser pointer does? It attaches to your gun to help you aim. It would make sense to make it so it doesnt set shit on fire or burn things when you're trying to get a clear shot, otherwise, the enemy would feel it.
The diode is powered from a buck converter in current regulation mode (about 105mA). The whole thing is powered from ATX power supply, 12V.
The collimating lens is adjusted to maximally focus the beam in about 5cm distance to light the matches. So in greater distance the light spot is big - the larger distance, the bigger the spot is. At 9th sec of the vid it is about 10mm in diameter.
oh well but it´s quite good for a self built one... but i think i´d prefer one to buy, because the collimation is much better and you just can power it with batteries (at least the handheld ones)
The collimation is set like this just to light the matches. After screwing in the lens a bit I can obtain a parallel beam of about 3mm diameter. The optics is the same as Axiz but black :) My driver can be powered from every battery that supplies at least 7V. To light this diode from lower voltage i just need different driver (with boost converter).
so in theory i could just power this whole thing with a car battery?
3 mm sounds pretty good for such a powerful laser... and i think at some point you just can´t say if it´s correct because the air scatters the beam...
Yes, in theory and also in practice you could power it from car battery, or even from 9V battery (I've made such violet laser pointer).
Yes, you're right. Rayleigh scattering at this wavelength is visible in such short distance as a few meters. So the beam isn't really parallel becouse it simply can't be in air :P
You can't make violet laser of DVD recorder - there's only a red diode. To get 405nm diode you need HD DVD or BluRay drive. If you'd like to make a burning red laser of DVD recorder, there's A LOT of video tutorials about it here on youtube.
make pop corn with the laser dude

Very nice, how does one make such a device and how far does the beam travel before it begins to split?

@DMPFace
LOL, beam doesn't split, why would it?

mam do ciebie 2 pytania
1. Czy mógłbyś gdzieś tutaj wstawić linka do układu zasilania lasera powyżej...
2. Czy laser z konsoli PS3 się nadaje...
Z góry dziękuję za odpowiedź

Can you see the blue beam clearly if you point the laser to the night sky?
andretodopoderoso7 2 years ago
Maybe not so clearly but yes, the beam is visible.

thats a blue ray diode.

No, it's a HD DVD diode. And BTW not 'blue ray' but 'blu ray' - without 'e'...

do you guys think it's just the batteries or is there something wrong with the diode?

If it still draws 110mA thent it can't be the batteries fault.

I think this is not from a hd dvd player this is a tactical laser pointer.

Also it's used in big rooms or sth similar to point sth on a map or whatever if u have a big distance from it!

@Xxero0 its not a 'gun' its a weapon. a gun is one of those plastic thing that squirt water

@Xxero0 if you were close enough to the enemy that they would FEEL the laser, then you are probably already dead. -.-

is the beam visible? ( because 405 nm is not as "bright" 532nm Green)
diegoribadacunha 3 years ago
whoa!
what supply voltage does it need?
and is that due to the camera or is the light spot rather big?
