Source Data of figure 4c for "Reconfigurable symmetry-broken laser in a symmetricmicrocavity"

1. This "Source Data" folder provides the corresponding experimental data files for figure 4c in the main text, including the figure, the raw data, the processed data, a source file of the figure, etc.<br>2. The "Source Data\raw data" folder includes the experimental results for the output intensity of chiral Raman laser under different linear coupling strengths of the Raman mode, namely the splitting of the doublet. The file name indicates the corresponding linear coupling strength, for example, the "2g_6.7584" file stands for the results with the mode splitting of 6.7584 MHz.<br>The file folder ("2g_***") is loaded with the repeated measurements under the same linear coupling strength. Each data file (data****.txt) contains two collection channels as the binary format from an oscilloscope: the first channel records the output intensity of the counter-clockwise Raman laser and the Raman mode transmission spectrum simultaneously, and the second channel records the output intensity of the clockwise Raman laser.<br>The specific data is the signal on the oscilloscope with the unit of volt, where 100 mV corresponds to the power of 17.379 microwatts for the Raman laser signal. Besides, the signal of the first (second) channel has an offset being 2.8 mV (31.5 mV).<br>3. The dependence of the chiral threshold power of the Raman laser on the Raman mode splitting can be extracted from the raw data and is shown in the "processed data.xlsx", as well as a modified standard deviation in each case. Here the standard deviation is obtained by considering the deviation from the mean value with a small distribution in the threshold region in each measurement. <br><br>
