We developed a new pulsed-coherent light source for wind sensing by combining a semiconductor optical amplifier (SOA) with a phase modulator that was operated to produce pulsed serrodyne modulation. Even though an SOA-based light source has the potential advantages of a small footprint, monolithic integration, and gain properties, instantaneous frequency deviation inevitably occurs, leading to measurement errors of wind velocity. We demonstrated the correction of such frequency deviation usingdoi:10.2184/lsj.45.11_714 fatcat:7gscgmntrnf7pmw3yhi5biysou
