  In a recent work, Bastin and Martin (B-M) [Phys. Rev. A 67, 053804 (2003)]
have analyzed the quantum theory of the mazer in the off-resonant case.
However, our analysis of this case refutes their claim by showing that their
evaluation of the coupled equations for the off-resonant case is not
satisfactory. The correct expression can be obtained by applying an appropriate
formulae for the involved dressed-state parameters.
