a Emission spectra measured at different pump intensities. The laser intensity (unit: 1014 W cm−2) is indicated on the corresponding spectrum. The laser intensity is estimated by measuring the size of focal spot in the case of linear propagation. b Typical angularly resolved spectrum of SC radiation.
