By "mining beam intensifier", I mean the upgrade that allows for faster terrain destruction. I believe this means the ability to faster mine massive nuggets of gold, Emeril, iridium, etc…
I can't make the upgrade myself, and don't wish to get a new tool to check the operation cuz mine's pretty good.
So what is "faster"? Shorter times between each disintegration? Greater volumes of rock disintegrated per second? Both?

The beam intensifier upgrade simply makes mining take less time due to faster disintegrations. The amount of mineral or resource output is not affected.
The upgrade makes it so that more is mined before you have to pause to let the mining tool cool down less, which makes mining large deposits take less time overall.
For a reference, check the wikia, though it isn't very descriptive.
EDIT:
I was curious to see the difference between the Beam Focus upgrades and the Beam Intensifier upgrades so I did some googling and found this:
This agrees with a post here as well.
