Extracting x, y and z coordinates from .las dataset (lidar)

Question

I was trying to extract bare coordinates of the points in a pointcloud of a classified (vegetation) .las dataset.

Using Arcgis and looking into the attribute table is not what I'm looking for so I was asking myself, if I can "de-convert" the .las to ASCII or so, to get those coordinates. I hope someone understands my question.

EDIT: I managed to get what I want with a simple toolset of Arcmap 10.2 called Featureclass Z to ASCII (3d Analyst)

Though you got you want in Arcmap, there is a free and open source way. To extract XYZ values from a .las file, check out LAStools, specifically the las2txt command:

$ las2txt -i mylasfile.las -o mytextfile.txt -parse xyz
