Dazzler
Description of Dazzler
Dazzler products are complete and ready-to-use systems for shaping ultrafast laser pulses, offering simultaneous and independent control over both spectral phase and amplitude.
The core technology behind the Dazzler, also known as the Acousto-Optic Programmable Dispersive Filter (AOPDF), operates through a longitudinal interaction within a birefringent crystal.
By utilizing a polychromatic acoustic wave and a polychromatic optical wave, this interaction enables precise control over optical signals spanning the hundreds of Terahertz range. Such control is achieved by manipulating RF signals in the tens of Megahertz range.
