Fig. 4

Examples of four types of input laser pulses in the LIDAR-EM experiment. Solid, dashed, dotted, and dash–dotted lines indicate rectangular, gaussian, ascending triangular, and descending triangular pulses, respectively. Widths and peak amplitudes are 60 ns and 120, 40 ns and 120, 70 ns and 150, and 70 ns and 150, respectively. The horizontal thick dashed line indicates the noise floor of the records
