Fig. 2: Modification of Nd: YAG via ion irradiation.
From: Optically pumped Milliwatt Whispering-Gallery microcavity laser
a Photograph image of the irradiated Nd: YAG crystal. Scale bar 2 μm. b Distributions of electronic energy loss (Se), marked as black cross, and nuclear energy loss (Sn), marked as red dot, versus the injection depth calculated by SRIM-2018. c–e display the SAED (selected area electron diffraction) image of Nd: YAG with different depths, marked as (i), (ii) and (iii) in b. Scale bar 5 nm−1. f Display the SAED image of the exfoliated Nd: YAG film. Scale bar 5 nm−1
