DATA & FILE OVERVIEW
--------------------

This dataset contains:

File name "Dataset_NALM.xlsx" contains data for 6 figures as presented in the article, the detailed as followed: 

Fig.2 measured spectrum of (black curve) Wideband spectrum , and (red curve) filtered spectrum with the fiberized Lyot filter.
Fig.3 (a) measured transmittance of the tunable coupler in the experiment and (b) calculated power-dependent transmittance of the NALM-SA with various coupling ratio (r) using the equation in the article.
Fig.4 (a) measured output power and (b) measured output spectra of the cavity at different pump powers.
Fig.5 (a) measured oscilloscope trace, measured radio frequency (RF) spectrum for (a) with 100-kHz span at the fundamental frequency, and (c) with 1-GHz span.
Fig.6 measured autocorrelation trace of output signal for (a) the uncompressed pulses and (b) compressed pulses with the grating-pair compressor.
Fig.7 (a) measured output power and (b) output spectrum measured at 1 hour time intervals for 6 hours.

METHODOLOGICAL INFORMATION
--------------------------

Description of methods used for collection/generation of data:

Relevant method to record each data is explained as followed;
Spectrum was measured by an optical spectrum analyser (OSA: AQ6375, Yokogawa)
Output power was measured by a power meter (Thorlabs)

Temporal pulse train was measured by an oscilloscope (MSO7104A, Agilent Technologies)
RF spectrum was measured by RF spectrum analyser (RSA3303A, Tektronix)
Photodiode used in the experiments was a 10-GHz bandwidth InGaAs photodiode (ET-5000F, EOT)

Pulse duration was measured by an autocorrelator (pulseCheck NX150, APE)

Methods for processing the data: The collect data was plotted using Origin. Relevant fitting (as explained in the article) was done by characterization in Origin.
