2.4 Intended use
The device is intended for driving of a RF-Driver with acusto-optical modulators (AOM). The RF-Driver must be
provided with inputs for the TTL-Signal (input low impedance 50 Ω or up to 10k Ωhigh impedance).
The device use FC-Fibre connector as Trigger –input for the pulses. For this a fibre coupler can be used which
guides a part of the output light (5 - 10 %) to input. Since an InGaAs-photodiode is built in the wavelength can
be between 1000 nm and 1700 nm.
Please store the manual near to the device and accessible for all users.
Furthermore, please take care that all necessary documents like laser safety regulations or country-
specific safety regulations are present.

3.2 AOM-output (SMA)
Output
Connector: SMA(f)
Voltage: TTL (square wave)
Current: ± 100 mA
TRise / TFall: < 1.5 ns
A driver for acusto-optical modulator (AOM) needs typical TTL voltage pulses for switching between the off
and on states. The exact value is given in the data sheet of the AOM –Driver.
The AOM-output is optimized for an output impedance of 50 Ω. Shortening the output may lead to
irreparable device damage.
The AOM-output is optimized for an output impedance of 50 Ω. For other output impedance values
the voltages are not correct.
3.3 AOM-MONITOR (OUTPUT)
Output
Connector: SMA(f)
Voltage: TTL (square wave)
Current: ± 100 mA

3.4 GATE-INPUT
Input
Connector: SMA(f)
Voltage: TTL/LVTTL
Frequency: < 100 MHz
Input impedance: 50 Ω
Minimum pulse width: 100 ns
The GATE-INPUT provide a logical AND-Function for the AOM-OUTPUT.

3.5 PHOTODIODE INPUT (TRIGGER-IN)
Input (optical)
Connector: FC (f)
Input Power: max. 10mW (cw)
Pulse Repetition Rate: max. 200 MHz
An optical pulse at the Trigger input increases a counter until a software pre-set value is reached. Then a TTL-
pulse is emitted at the AOM-output. The AOM-output pulse will have the pulse width and delay which was
pre-set using the software. The counter will be set back and counts again following the next Trigger input
pulses.
3.6 PHOTODIODE MONITOR OUTPUT
Output
Connector: SMA(f)
Voltage: Pulses < 2Vpp

4Use of the device
4.1 Unpacking and installation
Please verify the packaging if it is damaged. Any damage must be announced to the carrier and the
manufacturer after receipt. Please verify if the package is complete:
4.2 First steps
Connect the mains cable with the delivered power supply and connect the DC-Pug to the device.
Only use the delivered power supply!
Connect a USB A-B –cable with the device and your PC.
You may need administrator rights to install the necessary software drivers depending on the
operating system.
The software driver installation proceeds automatically if Microsoft Windows 7 or higher is used. For more
information please read chapter 4.3.

4.3 Installation of software drivers
A virtual COM-port driver is needed for the communication via USB. For systems of Microsoft Windows 7 or
higher the driver installs automatically if the PC is connected with the Internet. To do this you must only
connect the USB-cable. The driver installs automatically. It is not necessary to switch the SmartPicker AOM on.
This process can take some time.
For all other systems the drivers must be downloaded from the website of the driver manufacturer:
http://www.ftdichip.com/Drivers/VCP.htm . Please connect the USB cable after the drivers installation.
A new COM-port is displayed in the device manager of your system after successful installation.
You may need administrator rights to install the necessary software drivers on your PC depending on
the operating system. Please contact your IT-service.
4.4 Installation of LabView SmartControl AOM
The SmartPicker is controlled by SmartControl AOM Software.
For installation please start the setup.exe on delivered USB-Stick and follow the instructions.

System Settings:
In this section the system parameters for the picking regime is setup. With the Single Pulse Check you can
ensure that the system stops permanently when on the trigger input pulses are missed or skipped.
New pulse sequences can be generated by extracting single pulses or pulse bursts from pulsed lasers. This is
determined by the repetition rate of the signal source and the division factor.
The AOM´s operation principle and use are described in the AOM´s manual. Please contact our service if you
need more information.
Divider ... set up the divider for the input pulses
Delay … setup the delay from 0 to 1.000.000ns
Pulse width ... setup the pulse width from 0 to 1.000.000ns
Attention, Delay must be smaller than output period time
Attention, Pulse width must be smaller than output period time

SPC Settings:
For the Single Pulse Check an internal independent 100MHz clock is used. You may choose an appropriate
value for the check. For example:
Input frequency = 20 MHz
choosing 9 to ensure that asynchrony clocks not trigger the system and smaller then twice the calculated
number.
SPC –ON/OFF … activate the Single Pulse Check and show the actual state
Single Pulse Check … setup the value for the check 0…255
Save Settings … save system setting and spc settings actual values in the device
Limit Settings:
In this section you can use the additional Level Check to ensure signal quality and power at optical input port.
When activated the AOM Output and monitor Port is blocked in any case of limit error.
