Discussion Overview

The discussion revolves around identifying the most powerful laser systems currently available, with a focus on high power (petawatt regime) and high frequency lasers. Participants explore various facilities and their capabilities, particularly in relation to fusion experiments and military applications.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant inquires about the most powerful laser systems available globally.
  • Another mentions megawatt class lasers, specifically referencing Boeing's military systems.
  • A participant expresses interest in lasers with high power and high frequency, seeking the maximum product of power and frequency.
  • It is noted that the National Ignition Facility (NIF) has a Petawatt class laser for fusion experiments, with a suggestion that the duty cycle may be long and firing frequency low.
  • Another participant confirms the NIF's power capability, citing a specific output of about 3 TW and mentioning limited firing frequency.
  • A speculative question is raised about the feasibility of using these lasers for artistic purposes, such as writing on the moon.
  • Clarification is provided that LLNL had a Petawatt class laser that was shut down in 1999, with the NIF potentially reaching similar power levels when fully operational.

Areas of Agreement / Disagreement

Participants express varying levels of certainty regarding the specifications and operational capabilities of the lasers discussed. There is no consensus on the exact status of the NIF's laser or the feasibility of using these lasers for unconventional applications.

Contextual Notes

Participants mention the duty cycle and firing frequency of high power lasers, but these aspects remain somewhat unclear and are not fully resolved in the discussion.

I'd like to know where I can find the most powerful laser systems in the world right now. Anyone who's into this?

It depends a little on what type of laser you're asking about, but the http://www.boeing.com/defense-space/military/abl/flash.html and related systems are megawatt class lasers.

Thanks, interesting. What I'm most interested in is high power lasers (peta watt regime) and high frequency lasers. In fact I want to find a laser with as high (power*frequency) as possible...
 
I believe that the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory has a Petawatt class laser for it's fusion experiments. Lawrence Livermore had another one before that was shut down in the late 90s. I believe that when dealing with this class of lasers that the duty cycle is probably fairly long and that the laser doesn't fire with very high frequency. I could be wrong though.
 
Could we use any of these lasers to write our name on the moon? Perhaps give the moon the face of a beautiful woman?
 
LLNL had a Petawatt class laser that they shut down in 1999. I am under the impression that NIF would be at or near Petawatt class when it is done, but it could be the total of the 192 beam lines that gives that power.
