Absorption of ultrashort optical pulses in water

摘要

We investigate the linear propagation of 800 and 1530 nm ultrashort optical pulses in water. For all pulserepetition rates studied, we observe pure exponential decay down to a transmission of 2.5 X 10~(-5). We further demonstrate that previous observations of nonmonoexponential decay and pulse splitup in broadband pulses are consistent with Beer's law in the purely linear regime.
