Abstract: The invention provides a method for homogenized coherent excitation of a sample for determining molecular structure. The method includes selecting a monochromatic coherent light, homogenizing the monochromatic coherent light; irradiating the sample with the homogenized monochromatic light; collecting the Raman scattered light to obtain a profile and analyzing the profile to obtain chemical specific signature of the sample. The invention also provides a method for obtaining two dimensional imaging of a sample using irradiation of large sample area by homogenized monochromatic light without compromise in spatial resolution. A system for homogenized coherent excitation of a sample for determining molecular structure is also provided.
