Laser Accelerator Assembly

[philm]

Good evening everyone,


I have a few quick questions to ask the community regarding the Laser Accelerator Assembly. I read in the technical document that Stan was using IEDs (Infrared Emitting Diodes) with a maximum wavelength of 935 nm. Later, he switches out IED with LED. So, which one is it? LED or IED or both? I ask because Infrared does not have a wavelength of 935 nm so this caught me a little bit.


Also, has anyone researched into why he states an upper limit is 935 nm? I have also been trying to look online to see if there is an optimal wavelength to use and I came across line spectrum of hydrogen and oxygen. Does this have some relation to which wavelength would be best? I remember on Oxygen, there was one line that was brighter then the others and so, I am wondering if I should use that particular wavelength to get the best results.

So basically, if you had to boil it down, how can you determine the optimal wavelength for the LEDs of the laser accelerator assembly?

Thoughts anyone?

Good news everyone, I have found why the 935 nm wavelength was choosen.


Basically, it will take 1.23 eV for water to undergo photodissociation. This corresponds to a wavelength of 1008 nm. However, you need energy that is a little bit more then that. I went on digikey and the closest wavelength that you can get that they sell is 940 or 935 nm. 935 nm is a little bit less wavelength which means that the eV is a little bit more compared to 1.23 eV. Perfect! I believe this will work for the system


Now comes some more questions:


Would buying a 10 W IED or a 0.05 W IED make any difference in performance?


Instead of keeping the diodes always on, is it better to pulse them? (Has anyone tried this?)


Would a UV diode work also? (I am going to try this once I build my system and we will see. Unless someone else has already tried this.)


And so, the plot thickens.

Hello everyone,


I have another question concerning the LEDs/lasers. I am trying to find out where to put them in the system.


When I read the Stanley Meyer documents, I get the impression that the water is zapped with the energy before it undergoes the hydrogen fracturing process. However, I saw another person built a device which has the LEDs and zaps the gas with the energy. I am looking for some clarification, which interpretation is correct? Do I zap the water or the produced gas?
