Abstract
We studied the dynamic reflectivity and transmissivity of black phosphorus flakes using a pump/probe laser system. The flakes were excited with femtosecond laser pulses, ~60fs, in order to observe how the optical constants changed with respect to time delay. The relaxation time period of the excited charge carriers was calculated to be ~200-300fs during transmission measurements. Reflectivity measurements had shown longer time periods but could not be calculated due to limitations of the experimental setup. Future improvements to the system’s temporal range will be able to provide more detailed information about the longer lifetimes.
