Output voltage pulses in case of bipolar devices and for full bridge Pockels cell drivers

Fig.1 The output voltage pulse with magnitude U in case of bipolar module

The output voltage pulse with magnitude U is formed in case of bipolar module by applying +U/2 to the positive output wire and –U/2 to the negative one. For more information, check out the bipolar pulses diagram above. “Pulse delay” and “Pulse width” are usually measured at 50% level of the maximum. Rise and fall times are measured at 10-90% of the voltage level.

The output voltage result in case of the full-bridge Pockels cell driver topology (HVSW-03 and -04) represents pulses of alternating polarity by default. Output pulses with fixed polarity are an option for these drivers.
