IR Lasing Gold

[Seden]

I was reading this article on Nanotechweb.org (Sept.12,2007) entitled "When gold shines even brighter" and thought of Estebans IR Remote sensor. Don't know in any way if there's a relation but heres the link to the article:
http://nanotechweb.org/cws/article/lab/31120
and a quote from it "Excitation of films with the 795 nm fundamental of a Ti:sapphire femtosecond laser produces a strong white luminescence." The films from the quote are gold films. Now when you read it you will notice that there was some tuning involved depending on the thickness I believe but pretty interesting none the less.

Also speaking of IR, I've been following a thread on the Treasurenet Forum under "Techniques" whereby a fellow claims to use a camera with an IR filter to photograph ions on the earths surface at close range where metal has been buried for some time,anyone try this? I went an bought a IR longpass filter and tried photographing an area on my lawn where for the past 11 years I have been dumping my concentrates from placer mining and nada darn thing appeared on the IR picture no matter how I adjusted the settings on the GOOGLE Picassa software.

Comments on either or both?

Hmmmm...
I see the words "excitation", "gold" and "tuning" all came from the same article. This pretty much proves that gold has a frequency that can be tuned to, and that LRLs will locate the gold at distance. Doesn't it?

There is a much easier way to obtain instant results using an old digital camera. Digital cameras are sensitive to IR on their image sensors. In order to remove unwanted IR that spoils pictures, manufacturers put an IR filter over the image sensor. You can disassemble an old digital camera and remove the IR filter from the image sensor, then replace it with a visible light filter that passes IR. This has been done by hobbyists, using a visible light filter made from a piece of 35mm negative film that has been developed. They cut a piece of film from the opaque end of the negative roll of film, and use it to stop visible light, while passing IR.
You can see some details on how to do this online: http://geektechnique.org/index.php?id=254

The advantage to using a modified digital camera is you get instant results, and save the cost of filters, developing and printing, This means the digital camera can be used as a view port to look for sources of IR in relation to buried treasures. No need to wait for prints to be made.

P.S. Gold or gold concentrates dumped on the surface of the ground will not generate ions as gold buried beneath the ground. Scientists have discovered that gold ions are formed below the surface where gold-digesting microorganisms live and attack the gold with chemicals. These ions migrate upward through the soil until they reach 10-30cm below the surface. At this point, the ions become bound with the constituents of the soil (gold compounds, as in metallic gold, gold tellurides, or possibly organic compounds in extremely small amounts). Since your tailings never spent much time in contact with soil at the ion-generating depths, I doubt it has any ions around it. In fact, your IR photos proved it does not show an IR anomaly.

JPlayer,

I didn't remove the filter from my camera so thanks for explaining this. I paid and downloaded a book this englishman wrote on using IR to detect the soil signature of long buried items and the pictures looked very convincing so will have to buy an old camera and take out the IR blocking filter. Yeah I remember now why they did that. Guy's discovered that they could take pictures of clothed women and see beneath them,that was quite a hoot! I guess that would lend new meaning to the phrase "He undresses me with his eyes"

The book is entitled "Discovering Treasure Auras in the Digital Age by David Villanueva" which will set you back $19 to download,but a good read and interesting.

Why do I get the feeling that a new "off topic" thread is about to start?

I made this experiment: put an old IR shielded module into a plastic tube. I use at level of soil 30-40 cm and obtain signal of site just other pistols beeps, so the object emits!

Would not it be more productive just to search treasures instead o selling book telling how to do it?

Only if the technique really works.

Good point!

Reminds of the LRL/MFD concept and contraptions. If finding treasure with paint roller handles actually worked; wouldn't it be more lucrative to just use them - rather than trying to sell them to the gullible and technically-challenged???

Of course let's not forget... a paint roller handle does find treasure, exactly ONCE! When your money is deposited into the Wallet-miner's bank account.

After that, the paint roller handle is just a piece of scrap metal, having all the same treasure locating possibilities as random digging.

Just as you predicted this thread started going south with the usual crowd. Esteban thank you for sharing that information as you are one of the very few on Geotech that actually designs and builds things where others in their arm chairs just tap away on the keyboard with sarcastic comments.

Gentlemen,what do you think about the article I posted at the start of this thread from Nanotech.org? Did you READ it? Yes,no maybe,gonna do it?

Nice part about it is it's pure science. I really want your input that's why I posted it.

Randy...as I stated on that other website, I also own that book. In my opinion, it is worthless for the purpose of treasure hunting.

The book offers no validation from the scientific community, and its writing style is very amateurish.

Akin to something written by Dell Winders, the author boasts and brags about other successful means of treasure hunting. Such as dowsing, using Long Range Locators and Polaroid film. He also touches on seeing lights in the sky to find gold.

Two thumbs down for the realist or rational observer, but great for those sucked into conspiracy theories for finding big treasures.

Jim,

Since I actually got the steep skirted IR filter and tried it I now agree with you and Max/Robert (post above yours).

And as I stated on the other forum if it works fine (same with the upcoming 808nm laser for the lasing experiment) and hey I'm out a total of $60 which for 2 experiments isn't bad.
I do have an article from the California Mining Journal that you saw posted here and the other forum where IR between 700-900nm is valuable for Geological Remote Sensing which has been done for decades now so will invest in 3 separate bandpass filters for each (700nm,800nm+900nm)but for treasure hunting of NO value so far as I can tell until proven by yours truly. I am a part time gold placer miner and prospector so the above article will be yet another tool in my Geological tool chest.
Sorry I couldn't help you treasure hunters,

Randy

Hi Randy,
If lasers like yours have been used for decades in Geological remote sensing, then is seems you have a valuable laser for experimenting with. Aside from geological testing, there may be some application in experimenting with remote sensing of treasures. The time when buried treasure takes on the attributes of some geological conditions is when it resembles placer gold. ie: it has been buried for a long time. In this condition, you can expect the soil around where the treasure is buried is not the same as the surrounding soil. The difference may be small and hard to detect, but we have read reports that others have done it. Maybe by using your laser, you will have better results that people who used IR diodes.

Best wishes,
