A novel method to achieve phase-matched light amplification in a birefringent fiber via the three-wave mixing is proposed by using frequency shift change due to the stress applied to the fiber. It is confirmed that the signal power from a cw laser diode at lambda = 1.292 ..mu..m is amplified by 6.1 x 10/sup 3/ times in the birefringent fiber pumped with a Q-switched Nd: yttrium aluminum garnet laser at lambda = 1.064 ..mu..m. This will provide a new fiber-optic light signal amplifier having a good tolerance for variation of signal wavelengths.
