a–c Real-space image, angle-resolved PL, and interferogram of the cavity pumped by four laser spots (5.8 μm × 4.4 μm each) with centres located at vertices of a square with edges of 2.8 μm at 0.02Pth. d–f Real-space image, angle-resolved PL, and interferogram at 2.1Pth. White dashed ellipses in d indicate the positions of pump spots.
