Broadband high-resolution two-photon spectroscopy with laser frequency combs
Arthur Hipke, Samuel A. Meek, Takuro Ideguchi +2
Two-photon excitation spectroscopy with broad spectral span is demonstrated at Doppler-limited resolution. We describe first Fourier transform two-photon spectroscopy of an atomic…
Fourier transform spectroscopy around 3 microns with a broad difference frequency comb
Samuel A. Meek, Antonin Poisson, Guy Guelachvili +2
We characterize a new mid-infrared frequency comb generator based on difference frequency generation around 3.2 microns. High power per comb mode (>10-7 W/mode) is obtained over a…
Coherent Raman spectro-imaging with laser frequency combs
Takuro Ideguchi, Simon Holzner, Birgitta Bernhardt +3
Optical spectroscopy and imaging of microscopic samples have opened up a wide range of applications throughout the physical, chemical, and biological sciences. High chemical specif…
