LASUtility is a free download, and a free 5 day license is available (read the "Readme.txt" file in the downloaded directory for info on obtaining a license). The fact that it is a Java app also means that in theory LASUtility will run on platforms other than windows (the readme says Windows, Linnux, Solaris), but the download only includes a Windows executable.

Some users however lack access to software that will read the LAS format and thus would like to view lidar point cloud data in ascii format. ArcGIS) and all of the commercial lidar specific software read and write LAS data. Many of the major GIS software packages now support LAS (e.g. However, because LAS is a binary format, a reader of some kind is necessary to ingest the data, visualize it, or perform additional analysis. The ASPRS LAS format has become the standard for delivery of lidar point cloud data.
