Light Conversion's CRONUS-3P is a laser source developed 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, thus covering the biological transparency windows at 1300 and 1700 nm for three-photon (3P) microscopy. In addition, CRONUS-3P offers integrated GDD control and beam steering, as well as simultaneous 1030 nm output.
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, more reliable, and more 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.
