Abstract
We report an experimental study of dynamic coupling of two laser diode s (LD's) with a double phase-conjugate mirror (DPCM) in a Bi12TiO20 fi ber-like crystal. After the DPCM is recorded in the crystal, one of th e LD's is switched to the multimode regime, while the other remains la sing in the single longitudinal mode. Nevertheless, the DPCM produces phase locking of the single-mode laser with one of the longitudinal mo des of the multimode laser. Only the longitudinal mode survives after the transmission through the DPCM, demonstrating the coherence length recovery of the multimode laser.
