Abstract :
Ordinary self-pumped phase conjugate mirrors (PCMs) that employ stimulated Brillouin scattering (SBS) turn on when the gain exponent (G = gIL) is in the range of 25 to 30. Feedback makes it possible to reduce this threshold gain considerably. In this paper we describe several experiments involving SBS with feedback using focused, nearly diffraction-limited pump beams
