查询词典 Bosworth Field

By extending the VBG external cavity length, and inserting a convex cylindrical lens between external cavity and LDA for transmiting. Phase-locked of external cavity is achieved by tilting of Bragg Grating external cavity. Experiment studied the stability of the in-phase mode far-field output at 35A. Wavelength is locked at 802 nm. The Full-Width Half-Maximum of locked specrum narrowed to 0.2 nm and the corresponding far-field divergence angle is 1.8 mrad.
