Abstract

Self-pumped phase-conjugate (SPPC) loop resonators using four-wave mixing (FWM) in solid-state gain media are investigated in both injected and self-starting configurations. A model, using a transient treatment of FWM with the appropriate boundary conditions imposed by the loop geometry, allows us to analyze the threshold condition for oscillation, the temporal dynamics and the energy characteristics of such resonators. The influence of the input energy in the injected configuration, and the influence of the different gain gratings and output coupler reflectivity in the self-starting configuration are also analyzed. A SPPC loop resonator using FWM in a flash-lamp- pumped Nd:YAG amplifier is experimentally investigated. In the injected case, a maximum phase-conjugate reflectivity of 42, and a maximum extraction of 47 mJ are obtained. In the self-starting case, a TEM₀₀ mode output of approximately 130 mJ in a 13 ns single-longitudinal-mode pulse is produced up to 30 Hz. Experimental and theoretical results are in good agreement.
