You need to follow GeoTIFF specification in this regard.
libLAS links to libgeotiff to access GeoTIFF features necessary to handle
CRS/SRS. libLAS does not implement GeoTIFF specification itself - it would
be a big and painful task :-)
So, it's very reasonable to use libgeotiff.
I'd suggest to follow the same approach and try to find GeoTIFF
implementation in Java or perhaps there is Java binding for libgeotiff
