Extended Data Fig. 9 ∣

a, A schematic diagram of the deep GC (arrow) on the imaging axis. b, Comparison of the deep GC (~400 μm depth) imaging by 920 nm 2PM and 1300 nm 3PM. The maximum average power under the objective lens was 204 mW (80 MHz repetition rate) and 21 mW (0.33 MHz repetition rate) for 2PM and 3PM, respectively. Scale bars, 50 μm.
