Abstract
In this letter, the unitary and Hermitian phase operators for the sing le-mode electromagnetic field are given in the q-deformed case. A new kind of q-coherent states of a q-harmonic oscillator in a finite-dimen sional Hilbert space are introduced. Some properties of these operator s and q-coherent states are discussed.
