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 product for that keyword! High quality components are integrated into our designs to maximize lifetime, safety, and reliability. Both manufacturers and distributors can be registered. The interface drawing for both these devices is here in pdf format: Our Pockels cell drivers utilize solid-state MOSFET technology which provides excellent trigger noise immunity and a smooth output waveform.

It has been designed for high noise immunity and optimum signal integrity.
Get an ad package! 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. Both manufacturers and distributors can be registered. This requires a Pockels cell which is electrically well matched to the electrical driver source impedance across a wide frequency range. Pockels cells drivers for CW laser pulse slicing, cavity dumping in mode-locked lasers and Q-switching of nanosecond lasers.

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. Product entries of suppliers having an ad package are displayed with a logo, product description and product image.
Therefore there is a direct conflict between the requirements pocke,s fast switching and a large aperture and it is not possible to obtain ultra fast switching in large aperture cells. Click on a company entry to mark it. Of particular importance is the region centred at nm for use with Ti: By using this method, a clean electrical interface is presented to the driving circuit and internal reflections 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. 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. Contact us now to discuss your next project.
Oockels 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. Your products are not listed here? 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.
Sorry, we don’t have a supplier with that name! Obviously, as wavelengths increase, the voltage required for switching increases linearly and the driver power requirement therefore increases as fas square of the wavelength.

Electro Optical Components, Inc. 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 lockels and prevent additional laser pulses from being emitted.
Prove that you are a human being: The internal connections however present slightly too great a series inductance to truly match to 50 W.

Ultra Fast Pockels cells for pulse picking and pulse slicing applications from Leysop
So what makes the Celll different from other Pockels cells? Anyone, not only suppliers themselves, can report additional suppliers. Offering both a fast rise and fall time, it allows laser pulses to be injected into or coupled out of an amplifier cavity quickly.
