Laser SalesI want to terminate the laser beam after about two metres, like the laser swords in Star Wars. How can I do that?
Answer
It is not possible to create laser-sword like effects: You cannot "terminate" the laser beam somewhere, it can physically not be terminated without having an end-point (surface).
Light can not be ended somewhere, it can only "fade out", meaning intensity is reduced with greater distances. But this is of course not feasible for a "laser sword".
