QPP
The QPP electro-optic modulator selects individual pulses from a femtosecond pulse train. It is commonly used to control when pulses enter and leave a femtosecond amplifier cavity and to remove prepulses ahead of amplified pulses, improving nanosecond temporal contrast.

Pulse Generator
Sufastech
Number of Analog Channels: 2 Pulse Period: 5 nanoseconds - 8 seconds Time Base Resolution: 10 picoseconds
The PULSE RIDER series pulse generators (including PG-1072/1074 and PG-1501/1502 models) are high-performance devices launched by Active Technologies, based on patented FastEdge™ technology, divided into low-voltage high-channel (PG-1072: 2 channels, PG-1074: 4 channels) and high-voltage series (PG-1501: 1 channel, PG-1502: 2 channels). Low-voltage models output up to 5Vpp with edge times as low as 70ps; high-voltage models output up to 50Vpp with edge times as low as 400ps, both supporting single/dual/triple/quadruple pulse and other sequence generation, equipped with a 7-inch SimpleRider™ touch UI, easy to operate, capable of multi-device synchronization, suitable for professional testing and simulation scenarios.
