The Optical Pulse Amplitude Modulation. Representation of the optical pulse amplitude modulation paradigm e.g. for 1 kHz and 8 kHz laser modulation rate (LMR). For data comparability we opted to keep the laser pulse rate (LPR) constant over the different modulated frequencies in the presented sets of experiments. As a consequence, the number of pulses and the total energy per sinusoid period varied depending on the LMR as presented in Table 2. Increasing the LMR from 1 kHz to 8 kHz leads to a decreased number of pulses per sinusoid period. Increasing the LPR from 32 kHz to 50 kHz leads to an increased number of pulses per sinusoid and an increased number of pulses per stimulation unit.
