I wondered: Since Lightsabers are made out off light, and all other laser based weapons. Can't it be reflected by a mirror or something reflective?

No, it shouldn't be possible. The problem is that lightsabers aren't actually lasers (if they were, they wouldn't stop after 1-2m length, they'd go on until they hit something). They're some form of magnetic plasma bottle. The defences against them are magnetic or heat resistance (shields, dense metals, etc.), not reflection.

A surface which reflected charged particles would help, but the heat transfer would probably still melt it rapidly. (Lightsabers don't have much trouble with blast doors, for example, even shiny ones.)

(Even against laser weaponry, a mirror would be of limited value. The surface polish helps at first, but a sufficiently energetic pulsed laser will rapidly blow that shiny surface apart.)

    I recommend you make your hull out out of Mandalorian iron (starwars.wikia.com/wiki/Mandalorian_iron) – HNL Mar 15 '12 at 11:26
  • There is precedent for a reflective surface successfully deflecting a blaster bolt; IG-88 did with his palm shortly after he was activated - see starwars.wikia.com/wiki/IG-88A – PhilPursglove Mar 15 '12 at 11:57
  • @PhilPursglove: A blaster bolt only interacts with the surface momentarily; it's a small fast-moving pulse. A sufficiently shiny surface might do it. (It's still silly scientifically, but within the usual range of SW tech.) A second blaster bolt on the same point, however, ought to hit the scorch mark and, well, not reflect. (Also, IG-88 is made of very tough materials; that makes a big difference as his shiny surface was also designed to cope with incoming energy and damage.) – Tynam Mar 15 '12 at 14:13

    Technically the free electrons in the metal should act as a plasma (oscilating at the plasma frequency, in a similar way to the lightsabre) and deflect the blaster bolt. But various corrections to that model mean this is largely not the case. – AncientSwordRage Mar 15 '12 at 15:51
