  • Broadband infrared microscope objective and sample chamber
  • A) Broadband infrared spectrum (1.9 nJ/pulse, 171fs) measured to 2 cm^-1 resolution with a home-built Michelson interferometer. B) The spectrally integrated beam mode measured by scanning a 1mm iris 10 cm after collimation. C) The beam mode at the focal plane of the microscope measured by scanning a 5 um pinhole.
  • Alex aligns the broadband infrared source
