Abstract
In recent paper Cao et al. [Phys. Rev. B {\bf 67}, 161101 (R) (2003)] reported an observation of what is the first genuine multi-mode behavior in random lasers. They observed a splitting of a single lasing line into two lines with close frequencies when pumping is increased beyond a certain threshold. Here we are pointing out that the qualitative interpretation of these experiments given in that paper is misleading.
