资源简介：
Laser linewidth is a critical parameter reflecting spectral purity. To measure it, a delayed self-heterodyne method was employed using a 50-km-long single-mode fiber (SMF-28e) and a 40 MHz acoustic-optic modulator. The heterodyne signal was detected with an InGaAs photodetector (PD) and analyzed using an electronic spectrum analyzer (ESA) with a 1 kHz resolution bandwidth (RBW).
