利用具有极高光学灵敏度的激光二极管泵浦薄片Nd:GdVO4激光器，证明了自混合激光的多普勒粒度测定。光学移频器的重大改进导致了对水中浓度低至十亿分之五十（ppb）的262纳米聚苯乙烯乳胶球的布朗粒子的快速和准确的尺寸测定。用该自混合激光器成功地实现了亚纳米振动的实时测量。
Doppler particle sizing by self-mixing laser was demonstrated by using a laser-diode-pumped thin-slice Nd:GdVO4 laser with extreme optical sensitivity. A substantial improvement of optical frequency shifters led to quick and accurate sizing of Brownian particles with concentration as low as 50 parts per billion (ppb) for 262-nm polystyren latex spheres in water. A successful real-time measurement of sub-nanometer vibrations was also demonstrated with the present self-mixing laser.
