Optical sampling by cavity tuning
WebApr 22, 2024 · We use two Ti/sapphire pulse lasers from Mai Tai (Spectra-Physics) and Mira (COHERENT) as pump and probe light pulses, respectively. Their repetition frequency f r, wavelength, and pulse width are ∼80 MHz, 800 nm, and 100–130 fs, respectively. However, because the lasers are free-running, Δf varies with time and we directly measure Δf using … WebApr 12, 2024 · This paper describes a single-shot fluorescence lifetime imaging (FLIM) method. We use an optical cavity to create temporally delayed and spatially sheared replicas of the fluorescent decay signal onto a time-gated intensified charged-coupled device (iCCD). This modality allows different portions of the decay signal to be sampled in parallel by ...
