A method and apparatus for heterodyne detection of coherent Raman signals from a Raman active sample exhibiting a Raman-induced Kerr effect. More specifically, a method and apparatus is disclosed for generating a local oscillator output and heterodyning this output with a portion of a probe laser ou...
