Hi everybody.

This question is not directly about confocal microscopy but, and might be
better addressed on some electrical engineering forum. Bit i believe there
is someone who can guide me in the right direction.
I need to drive a Pockel cell driver with 10 V pulses, but available pulse
generator has max 5V output. I need pulses with submicrosecond rising time.
I have searched for level shifters chips with needed bandwidth and
impedance but all of what I found work up to 5.5 volts.
I wonder if someone can recommend some solution for the problem or give a
hint.
Thanks.
Petro.

What is the make of this 10V input driver -what is the input impedance? Do you have its circuit diagram so that it can be modified?

There are submicrosecond level shifters such as this:
https://www.onsemi.com/pdf/datasheet/mc14504b-d.pdf, and if the impedance
was high enough on the input you could even use a high side driver for even
faster switching speeds.  However, if you are driving a Pockels cell (which
normally requires analog instead of digital control) I would just use an
op-amp voltage multiplier.  A unity gain stable op-amp would be the easiest
bet, and one like this would be plenty fast:

Hi Mark
Unfortunately modification of the circuit is not an option. We have the
generator temporary id we will have to return it.
Best.

Thanks.
I will have a look on the shifter.
I am a bit lost by analog control?
Do you mean setting up the HT by control voltage?
Thanks.
Petro.

Dear Petro,

Would an amplifier solve your problem? If you buy an electronic amplifier that amplifies your driving voltage 2-3 times (from 5V to 10V or higher) you should be able to drive your pockels cell. Unless I’m thinking too easy here. You can buy suitable amplifiers from e.g. Minicircuits.

Best,
Nino

Maybe but it apparently needs a slew rate > 10V/us into what may be a 50 ohm impedance. This is RF circuitry. Perhaps the manufacturer can give some more details as it's hard to define what's needed on the basis of the supplied info. IMHO

What brand is the driver?  Is this modulation control or just on/off?

For these tasks an SRS SR560 comes in very handy, which can also be tailored for bandwidth. (No commercial interest, just a really useful multi-use lab accessory). But there are other excellent choices, too.

Hi Pedro,

I had a similar problem with an old AOTF which needed 10V but my homebrew controller based on an Arduino microcontroller would only deliver 5V max.
As a workaround I used a simple circuit with the TL084CN op-amp from Texas instrument, combined with the d/a converter  MCP4822. So the Arduino now deliver 0-5V via the MCP4822 which is translated to 0-10V by the op-amp.
Time resolution should be around 10µs but I never tested it.

Regards

JP

I was working on a high speed mux and came across this guy:

This would be perfect as it can convert 3V and 5V logic to up to 15V logic
and has a bandwidth of up to 40MHz with a 2A peak driving current.

Thanks Benjamin.
That looks like what I need.
At the end the producer said they will adjust the output.
Thanks to everyone for suggestions.
Best.
Petro.
