Preface
Acousto-optic modulators (
AOMs
) are an integral part of many mo-
dern
laser-based
experiments.
They
are
used
for
frequency
shif-
ting, amplitude modulation, and laser frequency stabilisation.
The
MOGL
abs
QRF
quad
RF
synthesizer provides a user-friendly device
that can simultaneously control four
AOMs
at once, with direct output
of up to 2 W per channel.
The wide frequency range (10 to 200 MHz) is compatible with most
common
AOMs
, and it provides high-resolution frequency, amplitude
and phase control.
The
QRF
provides analogue modulation of each
channel with 70 kHz bandwidth, ergonomic front-panel controls, and
ethernet/
USB
interface.
The included table mode allows generation
of predefined time-dependent waveforms. The
QRF
is is single small
(half-rack width) box which connects directly to AC mains power.
As you delve into this manual you will uncover more and more capa-
bility, but the microcontroller at the heart of the
QRF
allows software
improvements to add new features,
so please check the
MOGL
abs
website for updates, example code, and assistance.
We hope that you enjoy using the
QRF
, and please let us know if
you
have
any
suggestions
for
improvement
in
the
QRF
or
in
this
document, so that we can make life in the lab better for all.
