1. General Information

Please read this manual carefully. It describes the hazard the
user might be exposed to while using the product. It also explains
in details how to use the product in the safest and most efficient
possible way. The safety of any system incorporating the product is
the responsibility of the assembler of the system. Any actions
taken by the user that is not clearly described in this user manual
might present a risk and is the sole responsibility of said
user.

This product is to be used in laboratory or industrial tasks,
and only by personnel who have followed a training in laser
hazard.

This product is an OEM device for system integration. It is
designed for use as a component (or replacement) part and is
thereby exempt from 21 CFR1040.10 and 1040.11 provisions. Make sure
it is not put in operation before the machine in which it will be
integrated has been declared to be compliant with the relevant
requirements of the current directives.

1.1 Definitions

Caution: A caution is advised when dealing
with hazardous situations, tasks or objects, to prevent harm or
death and avoid material damage or failure.
Warning: A warning is given for potentially
dangerous situation for people which cause them harm or lead to
death.
Note: A note is a complementary piece of
advice that must be acknowledged by the user.

1.2 General Warning

Caution: The compatible laser sources used with
the AOM can deliver up to several Watts of coherent LASER
radiation. Always wear protective goggles and observe the safety
instructions provided by the laser diode supplier when using the

This product is an OEM device for system integration. It is designed for use as a component (or replacement) part and is thereby exempt from 21 CFR1040.10 and 1040.11 provisions. Make sure it is not put in operation before the machine in which it will be integrated has been declared to be compliant with the relevant requirements of the current directives :
· 2006/25/CE (following for example the regulation NF EN 60825-1) (Europe) · 21 CFR1040.10 and 1040.11 provisions (USA)

· Caution : Applying a maximum RF power (voltage) above the maximum efficiency can

lead to AOM permanent damage. As a first test level : a maximum RF power below

2W must be securely set.

5. Installation

Page 4/12 v3.3

5.1. AOM installation
1. Wear safety Googles 2. Wear a proper and working ESD wrist strap; 3. Caution : Set the module on a heat dissipating surface (an optical table works fine). Letting
the AOM in air with no dissipating surface leads to overheating and permanent damage. 4. The light can be inserted in any direction. The performance are the same (insertion loss,
extinction ratio etc.) 5. Caution : when using another RF driver, The RF power shall not be set over the maximum
diffraction efficiency level. A power over 2W can lead to a permanent damage. The RF power must be adjusted progressively from 0 V up to the maximum diffraction level.
5.2. RF Driver installation
The product is dissipated by conducting heat. The product shall be mounted on a metal structure using fixing screws. The mounting surface shall be flat with minimum size and thickness. A certain amount of space should be reserved around and above the product.
The product is powered by a DC of + 24V, and the power connector is supplied with a per-centric capacitor; The core of the heart capacitor is connected to the positive power supply, and the grounding sheet of the heart capacitor is connected to the negative pole of the power supply. The characteristic impedance of the product signal output port is 50 .
The product receives both external pure analog and/or digital modulation.
The adjustment of RF output power is achieved by changing the resistance of a multi-turner : turn clockwise to increase the output power, turn counterclockwise to decrease the output power.
1. Make sure the RF Driver has the correct RF frequency required by the AOM model (model 1 : 100 MHz, model 2 : 200 MHz, model 3 : 80 MHz ; model 4 : 200 MHz).
2. Make sure the RF Driver model is the one you need (TTL input or Analog input). 3. Connect the RF driver to the AOM with the SMA cable. If you use the modular model
RFAOM-TA-200, set the S1-S4 switch to the proper configuration (see below ) 4. Caution : Place the module on a heat dissipating surface (an optical table works fine).
Letting the RF driver in air with no dissipating surface leads to overheating and permanent damage. 5. Connect a 24V >0.5A power supply to the RF driver 6. Caution : The RF power shall not be set over the maximum diffraction efficiency level. A power over 2W rapidly leads to a permanent damage. The RF drivers power level (little
Page 5/12 v3.3

screw) is normally set in a safe area allowing a correct diffraction efficiency. If ever it is adjusted, this must be done progressively from 0 V up to the maximum diffraction level. 7. Connect the trigger signal and make sure you apply the good electric signal :
· TTL 5V-50 Ohm for standard RF-AOM-T-xxx model, · Analog 0-5V signal for RF-AOM-A-xxx · Any signal (0-5V or 0.1V) for the modular RFAOM-TA-200 model 8. If you need to optimize the insertion loss, apply a small optical CW signal at the proper wavelength and apply a CW trigger signal to the RF Driver. Use a screwdriver (Ø 3mm Multiturn) to adjust the RF power to get maximum optical power at the output of the AOM.
