Résumé : Efficient phase conjugation of 40-psec Nd: YAG laser pulses in Eastman Kodak mode-locking dyes A 9740 and A 9860 has been obtained. Variation of the phase-conjugate reflectivity with pump intensity is quadratic, without saturation effects, and variation with dye concentration agrees with a simple analytical model. We have used this reflectivity to obtain self-sustained oscillation and mode locking of a novel self-pumped phase-conjugate laser resonator. © 1981 Optical Society of America.
