Abstract
Aspects of the present disclosure generally relate to two-dimensional electronic apparatuses and methods of use. A two-dimensional electronic sum frequency generation (2D-ESFG) apparatus includes an amplifier including a laser source. A broadband optical parametric amplifier (BOPA) is optically coupled to the amplifier. The BOPA includes a two-stage amplifier. An etalon is optically coupled to the amplifier. The etalon includes two or more partially reflective substrate optical flats. A noncollinear optical parametric amplifier (NOPA) is optically coupled to the amplifier. A dispersive filter pulse shaper is optically coupled to the NOPA. A synchronizer including a galvanometer mirror is optically coupled to the BOPA, the etalon, and the dispersive filter pulse shaper. A detector is optically coupled to the synchronizer.
