Description
BOAR stands for Bimirror based Optical Autocorrelation with Retrieval. This new technique of ultrashort pulses characterization relies on interferometric single-shot autocorrelation and two photon absorption. The time delay is encoded into a spatial interferogram which is used to evaluate the pulse duration, the 2ω spectrum and the chirp. There is no non-linear crystal and no phase matching issues, the spectral working range is therefore very broad (1200 – 2400 nm). The BOAR facilitates simple, extremely robust, accurate and reliable measurements, which are spatially resolved and suitable for rather chirped pulses. Additionally, Fourier transformation allows direct retrieval in real time. Also, two models are available for two different temporal windows.
Key Features:
