[Abstract]:A Littman structure translational lens external cavity semiconductor laser using cage coaxial system is proposed and realized for the first time. The laser incident angle on the grating surface can be changed by the translation of the collimation lens driven by the micro-adjusting frame. The continuous wavelength tuning of about 8.5 nm can be achieved, and the 1 渭 m wavelength of the collimation lens can be changed about 0.02 nm,. The experimental data are in good agreement with the theoretical values. In this paper, the mode hopping of a Littman structure translational lens external cavity semiconductor laser is studied by the translation of a collimation lens driven by piezoelectric ceramics, and the basic principle of mode hopping is analyzed qualitatively. In addition, the output laser of the external cavity system has excellent single mode characteristics and stability. The single mode output power exceeds 18 MW when the operating current is 300 Ma at room temperature.
