Wow...badass! I love the design & how it looks too, very futuristic & smooth! I'm also interested in one of these & will keep an eye for when the owner posts sales info :beer:
 





He is a very cool and nice guy. Was a pleasure to do business with him. VERY patient...and very happy since yesterday :)

Glad you like the design. Its a joy to wield this. Very balanced. But the next gun-for-sale has to be simpler...simpler means more affordable ;-)
Mail me to discuss details!
 
So, you're not using the original flashlamp. You're applying 360V to it for an ouptut of "80-100J." What's the capacitance of the capacitor in your PFN? What's the actual light output of the lamp, or do you know that?

Most importantly, how do you know your pulse width?

Theres a formula for flashlamps. Gives you the resistance.
Some guy on SAMs Laser FAQ has made serious experiments with all kind of different input leverls. Voltage, Joules.

BTW: 80-100J is the INPUT...at 360V...
 
So, in order to have megawatt peaks, 1J of output needs to occur within a 1uS timeframe. That is an extremely optimistic duration, especially at only 360V.

How do you know this is actually occurring?

I GUESS I have 100-200 ns....so the output should be ABOVE 1MW.

Check out the laser faq. There is a table somewhere containing those infos.


Regarding the tattoo: Its the logo of Pantera...didnt escape my own mind, so I dont wanna use it actually ^^ Great fan though!

Sam's Laser FAQ - Commercial Solid State Lasers

That's what I've been reading.

First, it states that the optimum pulse for this rod is 100us. You claim to be pumping it with a pulse width between 1/500 and 1/1,000 of this.

Second, I noticed this table, where it seems you rounded 360V up to 400V to get 1.5% efficiency? Strange, nothing else in the table lines up with anything you mentioned... :thinking:

Code: 
  Vcap   Tinitial  Tfinal Delta T Calc Eout    Flashlamp Energy   Efficiency
 (Volts)  (Deg C) (Deg C) (Deg C) (Joules)  (Joules, from Pspice)     (%)

   400     23.7     28.3    4.6     1.13           73.6               1.5

   500     23.9     31.7    7.8     1.92*          112.0              1.7

There is only one mention of your range of "100 - 200ns" pulses, and I suspect that was actually a typo.

Rounded nothing. Its just a rough guess. This is a damn toy.
I have no idea what your intention is man. I already admitted, that its a theoretical value. And to be honest, noone cares ;-) its just for relation.

Utube-folks know blurays...and they know, they have 150-300mW...they wanna know how many output the gun has...its just for having a relation! For the non-laser-geeks.

Any further questions?
 
Okay...

Why are you trying to pass of a device that peaks at about a kilowatt as one that peaks at a megawatt?

Why are you selling a product to someone when you guessed at its pulse width and energy to make an even less accurate guess at peak power?

I have a guess... :p

Okay, you seemed to understand before, but I will rephrase...

If this laser really outputs a 1J pulse (it likely outputs a series of lower energy pulses), the pulse width is 100us at the lowest, meaning 10kW at most. Why try and say it's a MW device?

Why are you selling a product to someone when you guessed at critical things like pulse width and pulse energy? This gives you an even less accurate guess at peak power! I hope you didn't sell it to them saying that it has a megawatt peak; it most certainly does not.

he wants to say that you maybe sold a "Megawatt" device for the "price" of a megawatt, but the customer got only 10kW...

I think it doesn't matter as long an none of you realy measures the pulse shape and length.

I don't care.
Thats an awesome work youve done!
Maybe i get the time and the stuff to build a thing like this in the future.

Gut gemacht! Saubere Arbeit und weiter so!
 
xD you make me laugh. You seem offended.

Read....twice maybe. ON YOUTUBE...I wrote 1MW. Because its just an estimation.
I have 100J...so maybe 1-2J output. Dont know the ESR of my caps...used flash-caps.

Would you feel better if I would correct this little mistake? Noone gives a damn but you to be honest...
The buyer has NO information regarding pulse-power. Wasnt able to calculate...I would NEVER give away wrong infos to sell my stuff.
Not necesarry...believe it or not.

@LASERLIGHTER:
Danke..ich weiß nur einfach nicht wo sein Problem ist. Interessiert NIEMANDEN...und keiner der sich nicht wirklich damit auskennt, kann unterscheiden ob es ein MW oder 10kW sind. Pulsdauer bei 30J sollen 10ns sein...Lampe ist größer...
Lass es mich wissen wenn du deine fertig hast (schonmal was ähnliches gebaut btw)
Grüsse nach München.

As long as your buyer is okay with this, I don't care.

I'm glad estimates I make aren't off by factors of 1,000 - though I think I could get more undeserved attention from inexperienced Youtubers if they were. ;)

Is there any difference in burning power compared to constant wave laser ? Will this 1J pulse (let's say it's 1J) burn same as my 1.5W for 0.66s ?
