Dazzler - Acousto-opto Programmable Dispersive Filter
DAZZLER stands for Acousto-opto Programmable Dispersive Filter (AOPDF, Acousto-opto Programmable Dispersive Filter).
The inventor of DAZZLER is French scientist Pierre Tournois. He is the founder of the company FASTLITE and the inventor of the famous GTI mirror, a dispersion compensating element. The principle of its typical application of nonlinear pulse compression is shown in the figure below. A broadband pulse with positive chirp passes through a preset acoustic wave field. The long-wave (low-frequency) component is first diffracted and experiences a relatively long optical path. The short-wave (high-frequency) component is subsequently diffracted and experiences a relatively short optical path. Therefore, the effect of the acoustic wave field is equivalent to generating a negative chirp, thereby compressing the pulse.
This product is used in almost all mainstream ultrafast laser systems in Europe, and has also become a standard product in the products of well-known laser companies such as Amplitude Technologies, Thales, FemtoLasers, etc. Its compact size and powerful functions have won widespread praise from users.
In addition, by applying two or more acoustic wave fields with fixed phase and fixed time delay, multiple pulses with phase lock and fixed time delay can be obtained, which provides an ideal tool for spectroscopy research. This product has been widely used in mainstream ultrafast laser manufacturers (Amplitude, Thales, Coherent). Its compactness, practicality and user-friendliness have won it OEM and scientific research customers.
