Why Pockels Cell Drivers are Very Useful

Our drivers are designed for a variety of laser applications, such as cavity dumping, beam chopping, switching of flashlamp pump lasers, switching of lasers, pulse injection into an amplifier, or laser pulse picking that demands a quick rise and fall of the pulse. We also provide Pockels cell driver with quick amplitude modulation of HV pulses for use in pulse picking applications.

Higher voltage power sources are required for high-voltage drivers. Power supplies are available as standalone lab-style, OEM-style, or even combined with an HV driver into one device.

Different types of electro-optic modulators, which are managed by applying an electrical voltage, employ Pockels cells. The two electrodes of the Pockels cell are connected to some sort of Pockels cell driver, which provides that voltage.

In the field of laser technology, Pockels cells are frequently used for:

·         Active mode locking cavity dumping of continuous-wave or mode-locked lasers active Q switching, usually of solid-state lasers

·         amplifiers that regenerate for extremely brief pulses

·         pulse selectors for extremely brief pulses (e.g. for reducing the pulse repetition rate)

·         modifying laser beams, such as in a sinusoidal manner when it comes to laser stabilization

·         Depending on the application, the specifications for the electronic driver can vary greatly.

Today, the majority of Pockel cell drivers are produced using solid-state electronics and very high-voltage transistors. It could be necessary to stack many other several high-voltage transistors while being careful to achieve an even voltage distribution. On the other hand, when they are utilized improperly, drives can be destroyed extremely rapidly.

Considerations for Safety

For high voltages, it is always crucial to utilize good cabling with enough insulation. Regular checks should be made on the utilized cables for wear and tear, especially to the insulation, which is quickly damaged, for instance, in a laboratory or industrial setting. Electrical connector quality is also very important in this. In many nations, regular inspections are often mandated by law.

Pockel cell drivers must be handled carefully since they frequently generate electrical voltages that are dangerously high. Starting with an appropriate connection to their power supply, this is done. Fractional handpiece typically has a link to the public grid, thus it is crucial for them that their AC input connection is correctly grounded with appropriate, undamaged connections.

Devices with balanced bipolar outputs are a little less harmful because their voltages against the ground are lower.
