Request InfoFemto EasyBiprism-based optical autocorrelation with retrieval (BOAR) is a technique of ultrashort-pulses characterization from Femto Easy SAS that 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 2-ω spectrum, and the chirp. There is no nonlinear crystal and no phase-matching issues, making the spectral working range very broad, from 1200 to 2400 nm. The BOAR provides reliable measurements and is spatially resolved. The technique is suitable for...See full productRelated content from Photonics MediaPRODUCTSBioPhotonics Jul/Aug 2023 IssueVital Sign Measurement PhotodiodeThe TOPLED® D5140, SFH 2202 photodiode from ams OSRAM provides high sensitivity for wearable devices and vital sign measurement.
