Phase-conjugate reflection-induced spiking oscillation in a multimode LiNdP(4)O(12) laser.
Spiking oscillations were observed in a cw LiNdP(4)O(12) (LNP) laser coupled to a slightly tilted external beam splitter. This instability has been found to be brought about by the phase-conjugate reflection resulting from the resonant four-wave mixing in the LNP crystal.
