Ultrafast Degenerate Transient Lens Spectroscopy in Semiconductor Nanosctructures
We report the non-resonant excitation and Spray Arm Bush probing of the nonlinear refractive index change in bulk semiconductors and semiconductor quantum dots through degenerate transient lens spectroscopy.The signal oscillates at the center laser field frequency, and the envelope of the former in quantum dots is Snow Pants distinctly different fr
