Both manufacturers and distributors can be registered. The interface drawing for both these devices is here in pdf format: Sorry, we don’t have a supplier with that name! By using this method, a clean electrical interface is presented to the driving circuit and internal reflections are minimised. Q-switch drivers provide a fast rise time followed by a longer decay time.

Product entries of suppliers having an ad package are displayed with a logo, product description and product image. The internal connections however present slightly too great a series inductance to truly match to 50 W. If you are a supplier and want to be listed, please use the registration form. The capacitance of the Pockels cell is then of less importance as transmission line techniques must be used throughout the electrical system. By using this method, a celll electrical interface is presented to the driving circuit and internal reflections are minimised.

Pockels Cell Drivers

There are obvious limitations to this technique for ultra-short pulse generation, but it may still be useful for pulse picking. 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. If you like this buyer’s guide, share it with your friends and colleagues, e.

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. For pulse slicing applications, the requirements are more stringent still.


Buyer’s Guide … the one with the Encyclopedia! Not only are ceell very short sub ns pulses desired, but also the temporal shape of the optical pulse produced must be very clean with ccell overshot or ringing of the waveform. 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. Obviously, as wavelengths increase, the voltage required for switching increases linearly and the driver power requirement therefore increases as the square of the wavelength.

Ultra Fast Pockels cells for pulse picking and pulse slicing applications from Leysop

High quality components are integrated into our designs to maximize lifetime, safety, and reliability. 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.

Pockels cells drivers for CW laser pulse slicing, cavity dumping in mode-locked lasers and Q-switching of nanosecond lasers.

Of particular importance is the region centred at nm for use with Ti: Offering both a fast rise and fall time, it allows laser pulses to be injected into or coupled out of an amplifier cavity quickly. Contact us now to discuss your next project. The UPC still provides a moderately large aperture of approximately 5mm which is obtained by use of a 6mm diameter crystal.

Ideal for pulse selection and ultrafast laser regenerative amplifier designs up to 2. 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. 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.

You can obtain ad package for getting a much improved visibility and many more leads. Our Pockels cell drivers include the Q-series Q-switch drivers and R-series regenerative amplifier drivers.

It has been designed for high noise immunity and optimum signal integrity. This requires a Pockels cell which is electrically well matched to the electrical driver source impedance across a wide frequency range.

The design was conceived to minimize the time that the Pockels cell is exposed to high differential voltages and eliminate electrochemical degradation of the crystal, extending its useful life.

Rise-times achieveable with these devices can be easily obtained in the range of ps and upward with suitable electrical drive waveforms.

So what makes the UPC different from other Pockels cells? Well firstly, 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.
