摘要: We report on the development of a superresolution four-wave mixing microscope with spatial resolution approaching 130 nm which represents better than twice diffraction limit at 800 while retaining ability to acquire materials- and chemical- specific contrast. The enhancement is achieved by narrowing microscope’s excitation volume in focal plane through combined use Toraldo-style pupil phase filter multiplicative nature mixing.
