By using this method, a clean electrical interface is presented to the driving circuit and internal reflections are minimised. 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. Therefore there is a direct conflict between the requirements of fast switching and a large aperture and it is not possible to obtain ultra fast switching in large aperture cells. It is not however adequate to just ensure that the electrical pulse enters and exits the cell quickly. Options for enhanced reliability include complex voltage traces to avoid crystal degradation, custom triggering logic with precisely controlled delays to prevent damage and custom interfaces for remote control.

High quality components are integrated into our designs to maximize lifetime, safety, and reliability. It is not however adequate to just ensure that the electrical pulse enters and exits the cell quickly. Offering both a fast rise and fall time, it allows laser pulses to be injected into or coupled out of an amplifier cavity quickly. Our Pockels cell drivers utilize solid-state MOSFET technology which provides excellent trigger noise immunity and a smooth output waveform.

Pockels Cell Drivers
It has been designed for high noise immunity and optimum signal integrity. 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.
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. Ideal for pulse selection and ultrafast laser regenerative amplifier designs up to 2.

The internal connections however present slightly too great a series inductance to truly match to 50 W. RP Services and Tools. 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.
Most Pockels cells which use a 50 W r. You can obtain ad package for getting a much improved visibility and many more leads. All OEM designs can be built to the desired form factor and mounting requirements. One technique in common usage is to pass the laser beam through the cell twice, thus only requiring a quarter wave switching voltage instead of a half wave. Both manufacturers and distributors can be registered. Prove that you are a human being: 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 internal reflections on the sub-ns time-scale.
If possible, please provide a web address showing that this supplier indeed offers such products. Sorry, we don’t have a supplier with that name! So what makes the UPC different from other Pockels cells?
Of particular importance is the region centred at nm for use with Ti: Rise-times achieveable with these devices can be easily obtained in the range of ps and upward with suitable electrical drive waveforms.
Well xell, as mentioned above, the electrical parameters of the cell are matched to a 50 W impedance as is to be expected to be found on most ultra-fast rise time drivers. That form tast reachable with a link at the bottom of the supplier’s profile page.

However, with mode-locked sources often delivering pulse trains of greater than MHz repetition frequency shorter time windows are increasingly becoming more common. 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.
For pulse slicing applications, the requirements are more stringent still. Product entries of suppliers having an ad package are displayed with a logo, product description and product image.
