Future of lasers

[Singlemode Laser]

From that article :

It’s already been proven in the lab that subatomic particles can be hurled into the future at high speeds. An accelerator has been used on particles known to disintegrate after a certain amount of time. The particles appear in the future, in a young state, without having disintegrated over the usual time period. The particles’ aging slows down as they speed up.

Is this correct ? Maybe it's a mistake, or maybe an effect that looks like something it's not, and how far into the future are we talking about ?

Is this to do with a stream of particles that's going to be there anyway ?

I'm going to look into this, but it sounds wrong as presented, but also let me point out that the observed event is something happening in the future, probably fractions of a second into the future. Velocity time dilatation is real but only going forward, the disappearing into a blur at very high speed, well things moving really fast do look like a blur, and a super high velocity particle would age slower, bit that's still not going backwards.

This is what I meant with showmanship.

Time dilatation means that the "clock" of an object goes slowed at high speeds. The article now interprets a slower ticking time frame as something in the future. This is nonsense, as when you get "older" slower that in rest you still get older. No going back in time here whatsoever.

Generally relativity forbid time reversals.

I had to take a look at this since it has gotten some replies. Looks like a blatant ad to ask for donations for a feasibility study into what? A time machine? For someone who spent so long trying to learn general relativity, it looks like a ploy much more than a real possibility.

Exactly! We (in the US) have special funds for high risk, high rewards studies and projects. If his theory would have at least some scientific back up, he would have the money in a heart beat.

If something traveled backwards without being effected it's self it should be older....they just proved why no particle " went back " because it aged slower, as is expected in velocity dilatation.

Weren't they doing that at CERN? I am not smart enough to get into this subject. I have my beliefs but anyway this is very interesting.

Don't unplug the lasers for the driver. It is not good for either of them. If you want to kill a laser on this unit, just short the two pins on the TTL input for that particular color and it will turn off. That is the safe way to do it.

ive never owned a TTL laser what do you mean "short the two pins on the ttL input"? im thinking of getting one of these and just wanna make sure I do it right, thanks paul

I think it's crap, we can NOT travel back in time and CTC's are only a theory, but quantum entanglement is also something they keep proving that I think is flawed.

Yes, I agree.

I have the same laser, and I also have a large 532 with TTL and if you take the yellow and black wires "short" them, it will shut off the laser. I guess without damaging it. I love my little RGB it is neat. if you want a POWERFUL RGB get the laserlands 2000mw module it burns and it is very bright. but if you want to get your feet wet with an RGB that little one is great.
On the little unit, you will find three little sockets one red blue and green that is where you "short out" the TTL and turn which ever module off or on. You have to get the leads that plug into those little colored sockets

Yes, I agree.

Red i agree with you man, for some reason a lot of people believe that you can travel back and through time but i always think those people have watched "back to the future" too many times :crackup:

ah i see, that will be deeply noted, thanks dressur4 :beer:
i want to get one of those rgb modules so bad but ive got so many projects im working on right now lol. im sure ill get to it eventually.

 

[dressur4]

I always wanted an RGB laser I remember when they only were had by Krypton/argon and cost USED 20,000 and not much more than 2 watts Don't get wrong, I love my argons but they are so so inefficient but beautiful, Oh how the 90s were such a dark age of lasers and the cost good golly the prices back then. But I am here to tell you that both my RGBs are great and love them,,, I have a projector that uses RGB and love the colors. Mesmerizor or something like that. anyway good luck on your projects and hope you take a chance and get the little module at least. Tom

Here is a photo of one of these taken apart. If you look at the right side of the driver board, there are three two pin connectors....red, green and blue. These are the TTL inputs. If you short the two pins in any color you will shut that particular laser off.

looks like ill have to get one.
you should start doing your signature

thanks so much for this picture paul. I think I wanna get one now, ive been all over ebay looking for a pretty good deal on one, even if i blow it up i can at least salvage the dichros for future projects

 

[dressur4]

How do you . do your signature as I wanted to do that and don't know how... I am hoping to add a huge argon to my signature.

Richie, go to LaserLand's website. They are cheaper there than anywhere else I have seen them. Don't buy it on eBay as they are around $60.00 last time I looked.

 

[dressur4]

speaking of Laserland.... I see on their website, they do business with Coherent. wonder if they are telling the truth.. what do you think? I have ran my 300mw laser now today for an hour and no flicker or anything. fan comes on a little but cool as can be.. wonder if their higher end stuff is good.. I am pleased so far. hope it's what it apprears to be. If Basrem really makes some stuff for Coherent I would feel a lot better about my purchases..

Is your 532nm 300 mW a lab laser? It sounds like it from your description. I have a 230+ mW 532nm lab laser, but I don't remember who I bought it from. That was over five years ago. Do you have a photo of it? How much did you pay for it, if you don't mind my asking?

Let me try to post a picrure I took a couple. i will try to send attachment. BUT yes it is a lab laser and runs on 90-200 vac and love it. It won't upload and i have absolutely NO patience for computers that WON'T do what I want.. SO,,, here is the link to my laser. Oh I do not mind at all the cost was 248 with free shipping I love this laser. I am installing it in a Carlon electrical box made of lexan or PVC It will be so so nice when it's done here is the link

I also have to say,,, that shipping from China to my house which is out in the country took about two weeks and arrives with no damage. The Lili 50mw I ordered on Amazon took over a month..... the Qisc 450nm 2 watt took about 3 weeks and got stuck in customs and had to deal with that. So if Laserland lasers last and are as good as i hope they are the only company in China I will ever buy from.
