Abstract :
We demonstrate a new method of aberration-free time-to-frequency conversion through temporal lensing in a wave mixing process, for the spectrotemporal imaging and femtosecond pulse direct, real-time measurement. The nonlinear-spectronic reference pulse, self-shaped in a single-mode fiber, makes our technique a self-reference one.
