LAS format files with the extension is the interchange format as an alternative to ASCII (*. ASC) file that is currently widely used. About LIDAR can you read through wikipedia.
LAS file format for LIDAR data is said to reduce the file size by 35% to 80% compared to an ASCII file. LAS file this small impact on the speed of your computer to open and process the file.
