摘要
frequency-shifted feedback fiber laser oscillation and optical frequency domain ranging using a monolithically integrated tandem acoustooptic modulator driven by surface acoustic waves (SAWs) were demonstrated. The linear relationships between the beat frequency change and the optical path difference in the Mach-Zehnder interferometer with three slope,.; were obtained by combining file Upward and downward frequency shifts in the first and second SAWs.
