The relevant data of the Brillouin microlaser and second harmonic were simultaneously generated in the lithium niobate microdisk

The data include the spectrum of the Brillouin laser, the original data corresponding to the Brillouin laser threshold curve, the line width of the Brillouin laser, the Brillouin frequency shift, the Rayleigh scattering spectrum of the second harmonic light of the Brillouin laser, and the original data corresponding to the quadratic dependence curve of the second harmonic signal on the power of the Brillouin laser. The quality factors of the pump light mode, Brillouin mode and frequency doubling mode, the transmission spectra where the pump light mode and Brillouin mode coexist, including the transmission spectra of the frequency doubling mode.
