Abstract
We demonstrate picosecond time‐resolved pump‐probe experiments with subwavelength resolution using a reflection near‐field scanning optical microscope (NSOM). The sample was a laterally patterned gold nanostructure. Strain‐induced reflectivity changes as low as ΔR/R≊10−4 were detected in the near‐field.Keywords
