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. The capacitance of the Pockels cell is then of less importance as transmission line techniques must be used throughout the electrical system. Prove that you are a human being: It has been designed for high noise immunity and optimum signal integrity. Not only are often very short sub ns pulses desired, but also the temporal shape of the optical pulse produced must be very clean with no overshot or ringing of the waveform.

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. Options for enhanced reliability include complex voltage traces to avoid crystal degradation, custom triggering logic with precisely controlled delays faat prevent damage and custom interfaces for remote control.
High quality components are integrated into our designs to maximize lifetime, safety, and reliability. 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 pocels is possible to resolve internal reflections on the sub-ns time-scale.

That form pockelz reachable with a link at the bottom of the supplier’s profile page. Rise-times achieveable with these devices can be easily obtained in the range of pockeps and upward with suitable electrical drive waveforms. Electro Optical Components, Inc. Both manufacturers and distributors can be registered. Sorry, we don’t have a product for that keyword!
However, with mode-locked sources often delivering pulse trains of greater than MHz repetition frequency shorter time windows are increasingly becoming more common.
All OEM designs can be built to the desired form factor and mounting requirements. It has been designed for high noise immunity and optimum signal integrity.

The capacitance of the Pockels cell is then of less importance as transmission line techniques must be used throughout the electrical system. 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. 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.
Click on a company entry to mark it. So what makes the UPC different from other Pockels cells? Our Pockels cell drivers include the Q-series Q-switch drivers and R-series regenerative amplifier drivers. If you like this buyer’s guide, share it faxt your friends and colleagues, e.
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. By using this method, a clean electrical interface is presented to the driving circuit and internal reflections are minimised.
You can obtain ad package for getting a much improved visibility and many more leads.
Pockels Cell Drivers
Buyer’s Guide … the one with the Encyclopedia! 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. Not only are often very short sub ns pulses desired, but also the temporal shape of the optical pulse produced must be very clean with no overshot or ringing of the waveform.
Offering both a fast rise and fall time, it allows laser pulses to be injected into or coupled out of an amplifier cavity quickly.
Most Pockels cells which use a 50 W r. Sorry, we don’t have a supplier with that name! It is not however adequate to just ensure that the electrical pulse enters and exits the cell quickly.
Of particular importance is the region centred at nm for use with Ti: Product entries of suppliers having an ad package are displayed with a logo, product description and product image. The interface drawing for both these devices pockles here in pdf format: Q-switch drivers provide a fast rise time followed by a longer decay time.
