CRONUS-3P is an OPA-based laser source developed specifically for advanced nonlinear microscopy. It provides μJ-level sub-85 fs pulses at repetition rates of up to 2 MHz and tunable from 1.25 to 1.8 μm, thus covering the biological transparency windows at 1.3 μm and 1.7 μm for three-photon microscopy. CRONUS-3P has integrated group delay dispersion (GDD) compensation, ensuring optimal pulse duration at the sample, and optional automated beam steering to guarantee laser pointing stability.
