摘　　要：The external-cavity diode laser is advantageous in terms of low noise,high side-mode suppression ratio,high temperature stability,simple structure,and low cost,which has been the preferred scheme to realize wide-tuning and narrow-linewidth characteristics.Thus,it has been widely used in optical communication,lidar,environmental monitoring,spectral analysis,optical coherence tomography,and other frontier fields.Herein,we introduce the technical scheme and review the development status of wide-tuning and narrow-linewidth external-cavity diode lasers in detail.Primarily,the structure,working principles,and performance characteristics of external-cavity diode lasers are deeply analyzed according to different structures.The structural characteristics,key technologies,optical performance and application fields of state-of-theart studies in recent years are discussed.Finally,the challenges and potential development prospects of wide-tuning and narrow-linewidth external-cavity diode lasers are analyzed and discussed.
