Brillouin scattering has been measured with a high degree of sensitivity by a system built around a laser-diode-pumped microchip LiNdP4O12 laser. An efficient self-mixing modulation effect that is due to the interference between a lasing field and a weak field fed back from an acousto-optic modulator by means of a phase-conjugate reflection was used. Laser-Doppler velocimetry that can discriminate the direction of motion has been demonstrated.
