Prove that you are a human being: Your products are not listed here? This ensures that the waveform suffers no distortions due to electrical mis-match and cable reflections which could re-open the cell after a short time delay are minimised. Our Pockels cell drivers utilize solid-state MOSFET technology which provides excellent trigger noise immunity and a smooth output waveform. It is not however adequate to just ensure that the electrical pulse enters and exits the cell quickly. It has been designed for high noise immunity and optimum signal integrity.

Prove that you are a human being: The cost of high voltage drivers scale at a very similar rate in practice, so techniques to reduce drive voltage are important to reduce system costs. The interface drawing for both these devices is here in pdf format: Anyone, not only suppliers themselves, can report additional suppliers.
However, with mode-locked sources often delivering pulse trains of greater than MHz repetition frequency shorter time windows are increasingly becoming more common.
Of particular importance is the region centred at nm for use with Ti: Regenerative amplifier drivers have a square pulse with a fast rise and fall time, adjustable pulse width and may be operated to kHz or more. Well firstly, as mentioned above, the electrical parameters of the cell are matched fell a 50 W impedance as is to be expected to be found on most ultra-fast rise time drivers.
Product entries of suppliers having an ad package are displayed with a logo, product description and product image. Sorry, we don’t have a product for that keyword!
Considering the difficulty of generating fast rise-time electrical drive waveforms, it is especially beneficial that the voltage requirements be minimised and therefore the UPC is available in both single and double crystal versions.

Click on a company entry to mark it. Offering both a fast rise and fall time, it allows laser pulses to be injected into or coupled out of an amplifier cavity quickly.
The QDP-drive produces a double-pulse waveform that holds off lasing during flash lamp operation and pulses the Pockels cell at peak gain inversion— when laser output is at maximum — then applies voltage again to turn the Pockels cell off and prevent additional laser pulses from being emitted. It has been designed for high noise immunity and optimum signal integrity.
For pulse slicing applications, the requirements are more stringent still. Ideal for pulse selection and ultrafast laser regenerative amplifier designs up to 2.
Electro Optical Components, Inc. Our Pockels cell drivers include the Q-series Q-switch drivers and R-series regenerative amplifier drivers.
All OEM designs can be built to the desired form factor and mounting requirements. The capacitance of the Pockels cell is then of less importance as transmission line techniques must be used throughout the electrical system.

The internal connections however present slightly too great a series inductance to pockeels match to 50 W. Obviously, as wavelengths increase, the voltage required for switching increases linearly and the driver power requirement therefore increases as the square of the wavelength.
That is not to say that for normal Q-switching duty the response is in any way detrimented by the electrical interface, only that when used for ultra-fast switching applications it is possible to resolve pockdls reflections on the sub-ns time-scale. Q-switch drivers provide a fast rise time followed by a longer decay time. The UPC still provides a moderately large aperture of approximately 5mm which is obtained by use of a 6mm diameter crystal. Rise-times achieveable with these devices can be easily obtained in the range of ps and upward with suitable electrical drive waveforms.

Sorry, we don’t have a supplier with that name! For some applications however, the shortest possible risetimes are required and this is where our UPC design fxst. For uses and applications of Pockels cells like the UPC, look in the Application Notes section then give us a call to discuss your requirements.
In fact in most systems, the rise time of the electrical pulse generator into the load capacitance of the cell is the dominant factor and typical risetimes are thus of the order of 3 to 5ns.
