Introduction
The MOZZA is a multi-octave spectrum analyzer designed to measure accurately the spectrum
of infrared radiations in the range 1-4.7
µ
m. It is based on an acousto-optic tunable filter
(AOTF) and is specifically well adapted to pulsed sources such as femtosecond amplifiers, OPO
or OPA with repetition rate up to 640 kHz, however, it can also be used with high repetition
rate and continuous sources.
