Real-time observation reveals that the presented frequency shifts are non-adiabatic processes, unlike the reported extracavity settings.falseepsilon-near-zerofrequency shiftmode-locked lasersubwavelength thin filmtransparent conducting oxideVersatile and Efficient Dual-Range Frequency Shifts by Intracavity Epsilon-Near-Zero Nanolayerstext::conference output::conference proceedings::conference paper
