“…The quantities gðqÞ and f ðqÞ are the radial part of the large and small component of the bound-state spinor in momentum space. For the ground state of a hydrogenlike system of atomic number Z, the momentum waves are given explicitly elsewhere (Sørensen and Belkacem, 1994). By taking these in the limit aZ51 integration of (10) over angles yields the result…”

Nonlinear Chemical Imaging Nanomicroscopy: From Second and Third Harmonic Generation to Multiplex (Broad-Bandwidth) Sum Frequency Generation Near-Field Scanning Optical Microscopy

et al. 2002

The emerging field of coherent nonlinear near-field scanning optical microscopy (NSOM) is reviewed. Second harmonic, third harmonic, and sum frequency generation (SHG, THG, and SFG) are explored as means of providing chemically and environmentally selective probes with nanometer spatial resolution provided by scanning probe microscopy. Chemical selectivity is generated via resonant enhancement of the nonlinear signals, whereas interface vs bulk contrast is achieved by the order (even vs odd) of the optical process. A method of producing higher spectral resolution, and thus increased chemical selectivity, is also demonstrated in the form of near-field detected multiplex (or "broad-bandwidth") SFG (MSFG). Applications to biological and material samples are described.
