This case study is under development

Customer inquiry:
I am looking for a pulse picker or Pockels cell including driver and power supply to control the polarization (90 degree) of the output from Tsunami (80MHz centered at ~800nm). Cross polarized beams (50/50 in intensity) with ps delay using interferometer are supplied to the Pockels cell at 80MHz. And the pulse picker will be used switching
between these two polarized beams at a certain rep rate. The Both polarized beams with 50/50 intensity are required in my exp.

I need 2 different rep rates.
The first rep rate is for a train of laser pulses output with relatively high rep rate(~kHz). In this case both pulse trains of cross polarzied beams are required.
The second is relatively low rep rate with a single pulse output on single polarization. For both cases, I cannot afford any kind of circulating cooling system because of vibration issue.

The system should have proper input/output trigger signals with delay option for synchronization with other instruments.

Could you send me your product info for my experiment? Also please send me a price list with if any possible discount in your earliest convenient time.

Pismo pulse pickers

The pulse picker consists of the pockels cell, high voltage driver, synchronization and delay generator. It is suitable for single pulse selection from train of femtosecond or picosecond pulses. Also the device is used for pulse slicing in order to increase contrast.

  External high-frequency or optical reference
High-voltage pulse with adjustable delay
High-voltage pulse with adjustable amplitude
Two additional sync channels
High contrast
Low jitter

Applications
- Pulse selection
- Pulse Slicing
- Q-switching
