It is not however adequate to just ensure that the electrical pulse enters and exits the cell quickly. 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. That form is reachable with a link at the bottom of the supplier’s profile page. Of particular importance is the region centred at nm for use with Ti: Contact us now to discuss your next project. 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. Most Pockels cells which use a 50 W r.

Ultra Fast Pockels cells for pulse picking and pulse slicing applications from Leysop
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.
The Pockela 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.
Our Pockels cell drivers include the Q-series Q-switch drivers and R-series regenerative amplifier drivers. Sorry, we don’t have ecll product for that keyword! The capacitance of the Pockels cell is then of less importance as transmission line techniques must be used throughout the electrical system. Q-switch drivers provide a fast rise time followed by a longer decay time. Your products are not listed here?
Not only are often pockela short sub ns pulses desired, but also the temporal shape of the optical pulse produced must be pockells clean with no overshot or ringing of the waveform.

For some applications however, the shortest possible risetimes are required and this is where our UPC design excels. 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. Our Pockels cell drivers utilize solid-state MOSFET technology which provides excellent trigger noise immunity and a smooth output waveform. The internal connections however present slightly too great a series inductance to truly match to 50 W.
This requires a Pockels cell which is electrically well matched to the electrical driver source impedance across a wide frequency range.

High quality components are integrated into our designs to maximize lifetime, safety, and reliability. Get an ad package! Pkckels you like this buyer’s guide, share it with your friends and colleagues, e. Offering both a fast rise and fall time, it allows laser pulses to be injected into or coupled out of an amplifier cavity quickly.
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. So what makes the UPC different from other Pockels cells?
However, with mode-locked sources often pocjels pulse trains of greater than MHz repetition frequency shorter time windows are increasingly becoming more common.
Product entries of suppliers having an ad package are displayed with a logo, product description and product image. 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.
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.
Click on a company entry to mark it. It has been designed for high noise immunity and optimum signal integrity. Buyer’s Guide … the one with the Encyclopedia! There are obvious limitations to this technique for ultra-short pulse pockelx, but it may still be useful for pulse picking. All OEM designs can be built to the desired form factor and mounting requirements.
Rise-times achieveable with these devices can be easily obtained in the range of ps and upward with suitable electrical drive waveforms. That form is reachable with a link at the bottom of the supplier’s profile page.
Options for enhanced reliability include complex voltage traces to avoid crystal degradation, custom triggering logic with precisely pocksls delays to prevent damage and custom interfaces for remote control.
