Already on the tube, but I will show a few pics not included.

YouTube - REAL Pulse Laser Gun

That looks pretty cool. What laser do you have in it?

Thanks
It holds a modified SSY1 laser...not the US american model btw

How much is 1J of power in terms of mW/W?? this looks awesome! 250hours.. lol must suck for you heheh jks

Assuming the pulse-time is a few hundred nano-seconds, the peak power should be around 2MW.

I worked on it for about 1 hour per day...and in the end it was worth the time dont you think?

Yes for sure! looks great!

Nice high speed photo shots.... they look like meteor/comet impacts on
the surface of a planet..

I would have enjoyed seeing more of the internals of the gun...

Lawl... how many pulses do you get from that tiny 9V?

Should be in the description that its NOT 9V. The aiming-laser runs on 9V. The energy-storage is charged from 15V (10 AA-batteries)

Thanks laserbee: Was hard to get such nice pics. I have taken about 200 maybe more...
I added a pic showing the guts. Very early stadium of construction...forgot to make another one at the end of assembly before I put the housing on.

I hope you got adequate goggles .....

Fantastic job. What do you use for switching of the tank-cap, SCR, MOSFET, spark-gap?

^ you don't need to switch the tank-cap block, only the trigger, like in normal flash units.

Probably, he use a microswitch .... can try to guess, if it resemble like the one i made years ago, he's using an oscillator for charge the bank, the bank is connected fixed to the lamp, and then have a little capacitor closed on a HV trigger coil for the fire electrode, and maybe a digital or bar graph voltmeter for check when the charge of the cap bank is at the right level ..... just wondering, i don't have his schematic


Edit: just for the fun (and, before you ask, no, i'm not him )

I want one. To bad I'm not allowed to own weapons. That thing is definetly a weapon.

In numbers, how much W is that????

Very nice job indeed!

Did you make the optical cavity with the yag rod and flashlamp yourself, or is it something that you got pre-assembled?

Pulsed lasers are very beautiful (and this in particular is amazing) but I think that the continuous ones are much more fascinating

Depend ..... everything depend from something other ..... (J/K)


Ok, seriously ..... W are power, J are power in time, so, 1J = 1W/Second.

But for the cavity, you're usually indicating the power for the duration of the pulse (this i meant with "depend" ), so, if the pulse is the usual 100 microseconds, that is the pulse lenght that is normally used with the SSY1 assemblies, it means 1W/100 microseconds, that if you convert it in W/S, give you 10 KW (this, ofcourse, if the pulse was 1 second long ..... and, basically also mean that the power at the hitting point is equivalent to 10 Kw, but ofcourse, being long only 100 microseconds, the transferred energy is 1W)

Anyway, i doubt that a SSY1 assembly can last enough time at 1J output, cause that unit was designed for work around 50 milliJoule max ..... maybe it can last 20 or 30 shots, before the q-switch die.

A different thing is, if like me, Anselmo removed the q-switch ..... in this case, the pulses are no more regulated in lenght, and can also get 1 millisecond pulse, with 1 J of output energy, pumping the lamp with 25 or 30 J for a millisecond ..... but still this shorten the life of the assembly, especially the lamp and rod faces .....

So many replies...duude ^^
I modified the SSY...now it has a better flashlamp (longer arc) and yes the q-switch is still mounted. I give the gun a 2 minute rest MINIMUM during the shots.
I push 120J thru the lamp! The puls is damn powerfull. Pierces a cola-can and plastic-bottles...no matter which color.

If you wanna call it a weapon....thats fine with me. You cant kill someone with a device like that, maybe if I hit someones head with it.

I got a pair of goggles for EVERY laser I make. I am not stupid and mistakes happen...no risk.

Portable Co2 laser rifle is up next btw.

Portabe CO2 sounds like a next logical step. As the overall efficiency of CO2 is better, it could deliver more bang from the same battery power source, but i doubt it would be all that compact. I suppose all CO2 tubes usable for a portable version would be RF excited, carrying in a lot of extra electronics.

I wonder how it would compare on the fun/cool factor though. CO2 could give you much more average power, but probably not the very short and sharp bursts the q-switched yag provides, so the results might be less spectacular to watch.

Real nice -- I started on a SSY-1 into a Klingon disruptor housing a year or so ago. I used a camera flash supply adding a voltage doubler to the circuit but got distracted by other projects.... so little time .........
Mine still has the Q switch and I actually observed air plasma (pop) with a 5" FL lens. I chipped the lens on both sides :-(

HMike

By the way -- I have OD6 wrap around goggles for mine. This isn't a public display "toy" unless you have extra goggles.

Well Mike...seems we have the same strange thoughts about weapons and lasers know what I mean? xD

I used a cylindrical plastic lens for the pics...sold all my YAG-lenses -___- could kick my ass for this. But I guess 350V makes the puls way to long for an airbreakdown.

Benm: It will lool better than the gun...cooler housing...a lil bit bigger...will be 60cm long. Will burn wood, paper, melt ice and all this on a distance...maybe not the same bursts of fire, but already got a gun which can do THIS trick right? CW is the goal! Sealed, HV-driven, 7W...

That is soooooooo awesome!!!!!!! Keep up the great prodjects!

Thanks man.
Wait for the CO2 rifle...the gun will look like a toy compared to the rifle ^^

Woah man good job it looks freaking awesome

Thanks.

Thinkin about adding some pics of the different steps of assembly.
