Laser Pulse Detonation


Quote by redargon View Post
Also, if you put a laser on the ISS and then use it to generate a force on an object, is there a reaction force on the ISS at all?
There would have to be, as far as I know. Photons exert pressure, which is why the sail works in the first place. There would have to be, therefore, an equal and opposite force upon the launcher.

So you could put the ISS out of orbit unless you steadied it during launch using jets or something. Interesting. I think this laser launch module could be a pretty big one :smlie:

. If the mirror is left in proximity to the planet, and gravity holds it in place. .
This idea you propose might work, but as you know things left in orbit go around the planet and orbit , so the beam will not be constantly reflected back, this mirror or reflective surface will need its own fuel to maintain its position between the planet and the vehicle! Correct me if I'm wrong !

redargon and Danger !!

This is an excellent point you have pointed out ! Newton's third law, which I have avoided using because in space it causes a headache according to it, The ISS would have to exert an equal force at the "back" and that should solve the problem, so there will need to be a laser module and an extra fuel module, or this opportunity can be taken to launch TWO vehicles directly opposite to each other and avoid this problem !

, but what kind of mirror would you need to reflect such a powerful laser (I'm guessing it would have to be pretty powerful).
To answer the mirror question, well no MIRROR is 100% reflective, so some heat will be absorbed, the only way i can think of is :

To use a mirror with a material so the particles aren't close enough to trap the heat and allow the heat to dissipate away from the reflecting surface, and out the "back", another way would be to somehow cool the mirror without affecting its ability to reflect light, after all a laser is just another form of light, my knowledge of mirrors is limited, does anyone know if this sort of mirror exists or what type of material can be made for the back of the reflective surface ?
