The Light Conversion CRONUS-3P Femtosecond Laser System provides µJ-level pulses down to 50fs at repetition rates of up to 2MHz and tunable in the short-wavelength infrared (SWIR) range from 1250 to 1800nm, covering the biological transparency windows at 1300 and 1700nm for three-photon (3P) microscopy.
The CRONUS-3P laser source was developed specifically for advanced nonlinear microscopy.
It provides µJ-level pulses down to 50 fs at repetition rates of up to 2 MHz and tunable in the short-wavelength infrared (SWIR) range from 1250 to 1800 nm, covering the biological transparency windows at 1300 and 1700 nm for three-photon (3P) microscopy. CRONUS-3P also offers simultaneous 1030 nm amplifier and oscillator outputs.
Typically, multiphoton imaging in the SWIR range requires a complex multi-device laser system, a large optical table, and skilled staff. This reality encumbers neuroscience and other biomedical applications.
The CRONUS-3P system is a next-generation, industrial-grade, single-supplier solution that is more compact, reliable, and versatile. It achieves tunable femtosecond excitation with integrated group delay dispersion (GDD) control, ensuring optimal pulse duration at the sample, while industrial-grade design guarantees high pulse-to-pulse energy and long-term power stability.
