Sequoia’s state-of-the-art measurement technology allows femtosecond lasers to achieve unrivaled temporal contrast, ensuring the laser pulses have an ultra-short and well-defined duration. This exceptional temporal control is crucial in high-field physics experiments, where precise laser-matter interactions are essential for exploring fundamental scientific phenomena, such as laser-driven particle acceleration, attosecond pulse generation, and laboratory astrophysics.

The ability to accurately measure and optimize the temporal contrast of femtosecond laser pulses empowers researchers in high-field physics to achieve groundbreaking results with unprecedented precision and reliability. Sequoia’s integration with femtosecond laser systems enhances the capabilities of these lasers, making them indispensable tools for cutting-edge research in the most challenging and frontier areas of science and technology.

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.

Packed in a robust and compact housing, ready for air purge, the FTIRzz is an innovative Fourier-transform spectrometer with the unique ability to measure « low » repetition rate sources, and providing the fastest acquisition rate on the market.
Ideal for the measurement of OPAs and OPCPAs!

As an extension to our Mozza spectrometer, the FTIRzz is dedicated to the measurement of light sources from 1.6 to 12µm.
Whereas conventional FTIR spectrometer are limited to CW or pulsed sources at repetition rates above few tens of kHz, the FTIRzz is specially designed to measure all kinds of sources, down to 1kHz!

The FTIRzz also includes all common features of standard spectrometers, thanks to it’s user-friendly software.

Although primarily designed for OPA and OPCPA optimization and characterization, the FTIRzz is also perfectly suited to IR spectroscopy, and many other demanding applications requiring accurate and fast spectra acquisition rates in the MIR.
