Funnily enough, the links provided mostly talk about how to convert a laserscan into a pointcloud :)

Good catch. This is what happens when you have too many tabs open at once.

There is a package to convert pointclouds to laserscans - http://wiki.ros.org/pointcloud_to_las... . The parameters are documented on the wiki, and some sample launch files are provided in the package source.

This question tackles the same problem (but with velodyne pointcloud) using the pointcloud_to_laserscan package.
Here is another example of converting pointcloud to laserscan that you can checkout.
