Abstract:

A theoretical and experimental analysis of laser mode coupling and reactive Q-switching has been presented. In the forced mode locking situation, the total cavity electromagnetic field intensity Ez,t was expressed as an expansion of quasi-normal modes which satisfy the boundary conditions at both the fixed and moving mirror. Solutions of the wave equation indicated that the modes of operation were analogous to the phased locked oscillations of the phase-modulated laser. A peak mirror excursion of 1400 angstroms was used to mode lock a CO2 laser. Reactive Q-switching was obtained by modulation of the cavity length with a Mossbauer transducer. Regular Q-switched pulses were obtained at rates between 1 and 60 kilohertz. Author
