Not really ... since lasers and particle beams don't "explode" things, they burn through them.
However, you could use a laser or particle beam to destabilize a planet ... weaken a spot here or there, causing tectonic plates to shift or causing "super volcanoes" to erupt... or melting glaciers to cause flooding.
im sorry to say no not in game but that would be cool if want to do something fun but it would take a bunch of people and time is to blow up a small corporations pos find a mining pos there usually not too defended
No. The most powerful "beam weapon" known in the universe is the gamma ray burst caused by a supernova. If it were to hit a planet like Earth directly it would strip the atmosphere off and of course kill every living thing in an instant, but it would not destroy the planet itself.
