HIGH SPEED POCKELS CELL DRIVER
These industry standard Q-Switches are available in dry or wet versions.
Pockels Cell Drivers G&H
However, in simpler systems that just apply a voltage and then remove it, the fast removal can result in strain and the cell may not return high speed pockels cell its quiescent state for some time, related to acoustic time scales. To overcome this some Q switch drivers offer the possibility to switch beyond ground, i.
Please note that Kentech do not make pockels cells, but can supply them with systems or advise on type suitablility. High rep. General purpose 8. General purpose 4. Can your Pockels cell take a 50G shock high speed pockels cell being damaged?
Pockels Cell Drivers
Regards, Ed Miesak. These pockels cells are not high speed pockels cell for rugged applications, and unfortunately, we don't have the capability to test them for impact. I will reach out to you directly to discuss you application and if there is any data we might be able to offer that could help you estimate a maximum impact.
What is the damage threshold for a nm CW laser? Thank you for contacting Thorlabs. A techsupport representative will contact you directly with more information. While we don't high speed pockels cell a recommended driver model, I can reach out to you with contact information for some vendors our customer have used in the past for pockels drivers.
Does your product employ optic windows external to the KDP crystal? In addition, my application is purely pulse-redirection - I am NOT concerned with fempto or other spectral broadening effects due to piezoelectric phenomenon.
I will be requiring half-wave retardation, however requisite excitation amplitude, and requisite electronic slew rate, is of no concern our capabilities are beyond what's needed. While no significant electric current is required to high speed pockels cell a certain voltage at a Pockels cell, a substantial current spike needs to be supplied by the driver to rapidly change that voltage. Even the average currents can become substantial when operating such devices at high repetition rates of hundreds of kilohertz or even high speed pockels cell megahertz.
Both an excessive capacitance of the Pockels cell and a too modest current pulse capability of the driver can lead to a limited switching speed.

This can be problematic, for example when Q switching or cavity dumping a laserwhere serious performance degradations can result. Note, however, that the laser design and operation parameters also high speed pockels cell a profound influence on the requirements concerning switching speed. For fast switching e.
Electro-optic modulators rely on a change in the index of refraction for the optical wave as a function of an applied voltage. This requires a Pockels cell which is electrically well matched to the electrical driver source impedance across a wide frequency range. The capacitance of the Pockels cell is then of less importance as transmission line techniques must be used throughout high speed pockels cell electrical system.
Laviron, C. That voltage is supplied by some kind of Pockels cell driver connected to the two electrodes of the Pockels cell.
The requirements on the electronic driver can be very different depending on the application; see below for more details. Nowadays, basically all Pockels cell drivers are made based on solid-state electronic technology, using high voltage transistors such as MOSFETs. Multiple high voltage transistors may have to be stacked, taking care to achieve high speed pockels cell even distribution of voltage across those.
Device lifetimes can be very long, provided that properly engineered drivers are used with appropriate care.Leysop manufactures ultra fast response Pockels cells for pulse slicing and pulse For pulse picking (that is selecting one or high speed pockels cell adjacent pulses from a high.
