title: Lasers without inversion: interference of dressed lifetime-broadened states.
abstract: We describe the use of a coupling electromagnetic field to provide a general method of producing inversion-free laser systems. The interference between dressed states produces a zero in absorption while allowing gains of the order of that of the uncoupled system.
