From: Multi-port real-time observation for ultrafast intracavitary evolution dynamics
a The laser setup and (b) The detection system. Spectra from multi-ports are collected in time division multiplexed sequence. OIM optical integrated module, EDF erbium-doped fiber, PC polarization controller. PD photodetector, FBG fiber Bragg grating. c The multiplexed pulses train is well-resolved. d The narrow pulses generated by the FBG are used as the spectral triggers. e The stretched spectra.
