With a powerful telescope and a particle beam cannon on Mars we could deflect any incoming asteroids in plenty of time.

Assuming that they pass close to Mars before passing near or hitting the earth and that the bulk of Mars itself is not in the way. It would seem to make more sense to put such a cannon in solar orbit. It wouldn't have to worry about Mars getting in the way and if you have to move it you could. Also I'm not so sure it would work. Large comets or small asteroids can be big enough that an particle beam weapon that we are likely to produce in the next 20 years will be insufficent. We might need carefully placed nukes, or maybe a mass driver on the surface of the astroid that flings some of its mass away and subtlly alters the orbit of the rest. The main thing we would need is time. If we found out now that an asteroid was going to hit the earth we had better have atleast a decade of warning in order to build infrastructure to counter it. If we allready had a defense in place then the lead time we would need would be much less. The more lead time we have the less force would be necessary to deflect an astroid or comet enough to make it harmless.
