can we not DIY a photonic distruptor?

In reference to this:

Can we not DIY our own 'photonic distruptor'??? I'm sure it must be possible. What kind of lense do we need and what LDs do these use? How come this wavelength of light has such a great effect on a human's vision?

Thx guys.

Step 1-Get the $17 red laser module of dealextreme with a focusable lense.
Step 2-Focus the beam so it has horrible divergence and puts a giant red spot on a wall 20 feet away.
~photonic disruptor~

would that laser burn if you focused it correctly?

Razako,

I don't think so. I think the particular wavelength of laser used by the WL photonic distruptor has been specially selected as it has the most effect on our eyes. It also has very diffused beam. If we focus our beam 'big' we'll see lines in it.

Lol, its just like shining a flashlight into your eye, if you have dark adjusted vision your gona be blinded for a few seconds and after that you will have a big spot wherever you look making it hard to see.

That laser is the exact same as any other green laser, its just focusable so they can make it big and not permanantly blind the target.

Theres no way to make a green laser easily yet, since the only way is dpss which is very hard to get working.. at least until green diodes come out where pretty much out of luck trying to make our own.

...lazer.. ;D ;D ;D

i c.... thanks for that info about green lasers being dpss. I didn't realise that.

Guys,

The reason I created this thread was because I was trying to figure out why we can't DIY those lasers we see being sold on sites such as DX, WL, etc. etc.

I now realise it's because the lasers we DIY are diode lasers whereelse a lot of those being sold could be DPSS or others.

I also realised there's a complication of fabrication the lense assembly if we DIY.

Do correct me if I'm wrong.

Thx.

Comercially available diodes: IR , Red, Blu-Ray
Comercially available DPSS: Green , Blue, Yellow , Red , IR(1064)

If you want to DIY your own WL Photonic Disruptor just take the DX-200(or some other green laser) cut it up, fit the last lens with a threaded holder so it's adjustable, and fit the whole module in a waterproof case.I think the hardest part is to get it to be focusable while still waterproof, but I'm sure someone with some machining skills can pull it off.

thanks Switch. I'm gonna do a little bit of reading and research over the matter

Get a deal extreme true 50mw. then get the lasersaber.com tunnel gun. http://www.lasersaber.com/TunnelGun.html


BAM, photonic disruptor for cheap.

The tunnel gun is actually a spinning mirror on a motor and makes a laser-vortex/time-tunnel/whatever-you-like-to-call-it effect, it doesn't make it focusable.And it doesn't say it's waterproof, and it's designed to be used with WL products.Maybe the DX50 wouldn't fit.Besides, the photonic disruptor is 100mW(or so WL claims). :

You can also make a waterproof case with 2 lenses at one end(the last one adjustable) to put your favorite laser in and have all the key features of the Photonic Disruptor.

In their "future weapons" feature they show the PD mounted on a gun , but it doesn't say anywhere that it's shockproof.I bet the recoil of an M4 full auto fire would totaly mess up the crystal alignement in a standard green DPSS laser, maybe even the pump diode.

Cyclonite, the process is the typical green DPSS which produces 532nm light. Our eyes perceive green the most, so the same power of red light would appear far less bright than that power of green.

The very raw components to make such a unit wouldn't be too hard to obtain - just like its easy to obtain semiconductor grade polysilicon if you have some spare change. That doesn't get you any closer to making a waterproof focusable greenie than the silicon gets you to DIYing a processor though. Its not impossible, but it would take a lot of expensive equipment, knowledge, and experience to pull it off.

The rampant spread of AixiZ based red lasers seems to have made many of us a tad bit overconfident in our DIYing skills. Imagine if there had never been just one simple thing - the AixiZ 5.6mm module that acts as an all in one diode mount/method to hold the diode in alignment, light heatsink, and (most importantly), variable collimator. I bet there would be little to no real DIY going on. How else would the masses get their diode up and running in a convenient collimated setup? Only well qualified machinists with at least a basic knowledge of optics would be able to pull it off.

Thanks so much that's a fantastic explanation. Appreciate your effort. Yeah from what I've read and seen, it seems like the only reason the masses can DIY red / infrared lasers are because they are diode based and the AixiZ module takes them in and provides a variable focus lense. The driver circuit for a diode based laser is also much more simple.

I'm trying to understand 1 more thing. What does it mean by 'pulsed' power supply? From our Sony 16x diode spec sheet I gather that they can be 'pulsed driven' as well? I hope that someonec an shed some light here so that I won't have to open up a new thread just for this quick question.

Thanks once again.

Cheers.

pulsed means the laser is turning on and off many times per second, the reason this is done is that the diode normaly "peaks" when it's first turned on, then goes down to its average, so with pulsed the laser is always operating at it's peak power or near it. I'm not sure i'm 100% correct so anyones free to correct me if i'm wrong.

thx. can someone please confirm that? also, how will a pulsed driver affect the temperature of the diode? will it get hotter?

thx.

I actually think the diode will stay cooler because half the time it's being used, it's actually off. So it does have time to cool. But I don't really know much about how pulsed operation works.

Actually, basically any green laser can be made into a "photonic disruptor" as long as the lens is adjustable (or can be made adjustable). My X105 broke and After fixing it I was going to make it externally focus adjustable. The collimator in it was glued to a threaded plate that could easily be adjusted. I decided against it because I was lazy but making it externally focusable would be pretty simple. Since I didn't mod it, if I want to adjust focus/collimation I just have to twist the collimator with a screwdriver or something (which isn't hard) but I never use it to blind people anyway. But sometimes I like to focus it to make burning more fun...
Anyway...
The hardest part would be making it waterproof. But how often do you use your laser in the water anyway?
