The Light Conversion CRONUS-2P three-channel tunable femtoseond laser system is the ultimate source for nonlinear microscopy.
This industrial-grade femtosecond laser system provides watt-level, three synchronized outputs with high repetition rate, short pulse duration, and GDD control.
The CRONUS-2P femtosecond laser provides watt-level three synchronized outputs, offering a high repetition rate, short pulse duration, and GDD control.
CRONUS-2P is the ultimate source for nonlinear microscopy.
In standard configuration, the two independently tunable outputs, operating separately or simultaneously, cover 680 – 960 nm and 960 – 1300 nm, respectively, while the third is fixed at 1025 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.
