World's Newest, Most Powerful Laser Comes Online

deglr6328 writes "The OMEGA EP laser at the University of Rochester's Laboratory for Laser Energetics was dedicated today at the Robert L. Sproull Center for Ultra High Intensity Laser Research. The new laser, which has been in design since ~2002 will, at 1 kilojoule per 1 picosecond pulse, be the highest energy petawatt-scale laser ever created by far. For a fleeting fraction of a second, it will deliver a beam of infrared light at 1054 nm that is more powerful than the total energy consumption of all human activity on the planet, to a tiny spot the size of the head of a pin. Previous petawatt scale lasers such as the one created at Lawrence Livermore labs in the late '90s and (dismantled in 1999) were capable of only several hundred joules per pulse.

needs more shark

wheres the most powerful shark, step on up!

If the USAF had a sense of Humor...

wheres the most powerful shark, step on up!

If the US Air Force had a sense of humor, they would name the YAL-1 [wikipedia.org] "Shark."

Don't be too proud...

...of this technological terror you've constructed. The ability to generate a 1 kilojoule per 1 picosecond pulse is insignificant, next to the power of a good Slashdotting.

Re:Don't be too proud...

Perhaps one day ISPs will be able to capture that energy and use it to power their data centers. It would be green energy in more ways than one! ;)

don't disparage the slashdot effect

You have been warned!

The most intense is a UK Laser.

The Central Laser Facility in the UK has a laser Astra-Gemini that will produce a greater intensity on target. It is a dual beam laser with a repetiton rate of 3 shots per minutes.

The building to house this laser is like a small house but with a shielded room for the target area.

- Astra- Gemini : 15 J on target in 30 fs : Single Beam Intensity to 10^22 W/cm2.

- OMEGA EP : 1 kJ in 1 ps; on-target intensities of greater than 2 x 10^20 W/cm2.

the pico second ignition should be called slow ignition compared with 30 femtosecond.

oblig

to a tiny spot the size of the head of a pin

... from the head of a frickin' shark, obviously...

Mini-me...

...stop humping the world's newest, most powerful "laser".

And once again science reporters gets it all wrong

"The new laser, which has been in design since ~2002 will, at 1 kilojoule per 1 picosecond pulse, be the highest energy petawatt scale laser ever created by far. For a fleeting fraction of a second, it will deliver a beam of infrared light at 1054 nm that is more powerful than the total energy consumption of all human activity on the planet,"

More powerful than the total ENERGY consumption of all the human activity on the planet? It's only one kilojoule. It would be much more accuracte to say that the POWER output for a picosecond would be greater than the combined POWER consumption of the entire planet.

But that raises another question: Do most people understand the difference between ENERGY and POWER, anyway? the two words seem to be used almost interchangabily by your average Joe.

Re:

Actually (although I hate to reply twice) I've just noticed something in your statement that doesn't sit quite right.

You've said "POWER output for a picosecond would be greater than the combined POWER consumption of the entire planet"

I'm not a physicis

Re:And once again science reporters gets it all wr

isn't Power Energy per Time, thus Power output for a picosecond is Energy per Time per picosecond?

You're right in that power is energy per time, in this case the energy is one kilojoule and the time is one picosecond, so the power is one kilojoule per picosecond.

What the GP means is that, during that interval of one picosecond, the thing is emitting more power than is being consumed by all the planet. The total energy emitted by the laser pulse is that power multiplied by one picosecond, and the result of this multiplication is one kilojoule.

An interesting bit of information here is a round figure for the power consumption of all humanity: one kilojoule per picosecond. To get the equivalent in kilowatts, multiply one kilojoule by 1000000000000, because a kilowatt is one kilojoule per second.

Re:Hey you guuuuuuuuyyyyyssss!!!

It works more like this. Imagine water flow. Amps are the area of the cross-section of the pipe. (This is why Amperage determines wire thickness. If the wire isn't as thick as the cross-section then heat will build up. Not good.)

Volts are the pressure on the water (think length of pipe's worth of water per second. That's pressure. Regardless of the diameter of the pipe, the same length of pipe's worth of water will come out per second at the same pressure. Same thing with Volts).

Watts are volts times amps which in water equivalent would be like volume per time (that's what you get when you multiply area by length/time). Multiply Watts by time and you get energy (measured in Watt-hours or whatever).

don't forget political power

How many jewels do you need to get that?!

 

Re:And once again science reporters gets it all wr

Step 1: Store 1kJ in a tank of capacitors
Step 2: Short the terminals
Step 3: ???
Step 4: You just consumed the total power output of a power plant for a very small fraction of a second.

(The ??? step can be anything, your capacitors might explode and kill you if you have bad karma.)

Warning Sign

"Do not stare into laser with remaining eye."

OT : Coincidence?

Is it just a coincidence or does this story have anything to do with the fact that yesterday Google had lasers on its main page (which I assume commemorated to 50 years of the creation of lasers, either that or "first laser!" must be the latest new Internet fad)?

forget the sharks!

Where's the KABOOM? There was supposed to be an earth-shattering KABOOM!

World's Newest, Most Powerful Laser Shark Created

The OMEGA EP laser shark at the University of Rochester's Laboratory for Bioenergetics was dedicated today at the Dr. E. Vill Center for Ultra Evil Laser Shark Research. The new shark, which has been growing since ~2002 will, at 1 kilojoule per 1 picosecond pulse, have the highest energy petawatt scale laser ever mounted on the back on a shark, by far. For a fleeting fraction of a second, it will deliver a beam of infrared light at 1054 nm that is more powerful than the total power output of all other shark activity on the planet, to a tiny spot the size of the head of a pin. Previous petawatt scale shark lasers such as the one created at Lawrence Lawless labs in the late 90's (and dismantled in 1999) were capable of only several hundred joules per pulse. The new OMEGA EP laser shark will be able to manifest power densities sufficient to exert power over various just-above-soon-below sea-level countries and will have the capability to directly attack nuclear submarines through ultra high electric field initiated photodisintegration.

Someone's Sig - It Needs To Be Said

Not impressed

What do you want to shoot today?

Worlds biggest laser online? Cool. What's the IP?

Manhattan Project

Thanks to this breakthrough the sequel to the 80's movie "The Manhattan Project" will be 90% shorter with 300% more John-Lithgow-Scrunched-Up-Nose per cm2

The six most exciting words in the article

"ultra high electric field initiated photodisintegration"

Gawd, I get a chubby just thinking about that.....

In layman's terms

you take a car battery and discharge all of its energy in a picosecond or less, and for that split second, you are generating as much power as this laser.

Big deal.

Re:Enough stupid shark jokes

That movie is 11 years old now. The joke is dead.

Good jokes die with age. Bad jokes instead, become more powerful than you can possibly imagine.
