Ultrafast probing of the complex refractive index in an active mid infrared quantum cascade laser

Time and phase resolved spectroscopy of broadband mid infrared pulses transmitted through the active medium of a mid infrared quantum cascade laser reveal the full complex refractive index and its derivatives over a wide spectral range. Using electro-optic sampling, we can monitor the optical respon...

More Information
Summary:Time and phase resolved spectroscopy of broadband mid infrared pulses transmitted through the active medium of a mid infrared quantum cascade laser reveal the full complex refractive index and its derivatives over a wide spectral range. Using electro-optic sampling, we can monitor the optical response even above threshold and study effects of gain depletion and decoherence.
