Description

CRONUS-2P is a three-channel tunable femtosecond laser providing watt-level three synchronized outputs with high repetition rate, short pulse duration, and GDD control, making it the ultimate source for nonlinear microscopy. In standard configuration, the two independently tunable outputs, operating separately or simultaneously, cover 680 – 960 nm and 940 – 1300 nm, respectively, while the third is fixed at 1030 nm and is accessible in parallel. Thus, 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 two tunable and simultaneous channels 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 configurations:
