CRONUS-2P is a femtosecond laser providing three simultaneous and synchronized outputs with high repetition rate, high output power, short pulse duration, and GDD control, making it the ultimate source for nonlinear microscopy. Two outputs are independently tunable in the 680 – 960 nm and 960 – 1300 nm ranges, while the third is fixed at 1025 nm. The CRONUS-2P can be used for simultaneous excitation of multiple fluorescent probes, calcium indicators, or opsins at their absorption maxima, whereas second- and third‑harmonic emission (SHG and THG) can be spectrally shifted for ease of detection or resonant enhancement.

The three simultaneous outputs also enable advanced coherent anti-Stokes and stimulated Raman scattering (CARS and SRS) applications with dual-band imaging, a broader selection of vibrational resonance frequencies, constant-difference dual‑beam tuning, resonant enhancement, and more.

CRONUS-2P is a fully automated and robust next-generation laser system built on over 25 years of experience in designing and manufacturing femtosecond lasers and wavelength-tunable sources.
