A previous question asked about the feasibility of reflective flakes of metal suspended in the plasma to absorb heat from the plasma and radiate it for cooling the craft: Plasma-shell and suspended flakes for cooling... As this initial question seems to be at least feasible, i.e. not violating any laws of physics, this follow up question asks about re-suing the configuration to drive a laser...
Is it possible to use the energy from a plasma-envelop to power a laser...
Background: SciFi book set 50-100 years into the future.
Spacecraft are able to control, with a high degree of precision, plasma envelopes surrounding them. This is used in-atmosphere for magnetohydrodynamic propulsion. In space, the plasma-envelope is used for stealth by absorbing/reflecting radiation from radar etc
radiator flakes suspended in plasma
My Question: In a hot plasma, assuming the flakes could be oriented to form a 'laser cavity', would it be feasible for the ship to use the energy stored in the plasma to drive a Laser? The laser cavity would be external to the hull, similar to a the concept of a 'stellaser' see here and this answer on quora which uses the atmosphere of a star to drive a very powerful laser to push sail-craft between stars.
laser 'cavity' in the plasma envelope
The laser would 'drain' the energy from the plasma for cooling, but also the beam could be used for offensive, defensive, and point defence purposes.
Edit: I am still hoping for more answers to the question if anybody has some thoughts.
Some additional detail:
- What would be the main technological issues to be addressed with this configuration? e.g.
- is super high 99.999% reflectivity of the flakes pre-requisite?
- could non-linear magnetic/electric effects feasibly be harnessed to position the flakes assuming arrays of superconducting coils in the hull and pseudo crystal behaviour of the flakes?
Note: the 'intellects' of these ships are very smart so they could be constantly tweaking the plasma like a stellerator.
Many thanks in advance! I am happy to share more info!
