Frequently Asked Questions

The picoEmerald is a two-color turn-key system that provides fully automated temporal- and spatial-overlapping ultra-short pulse trains for Coherent Anti-Stokes Raman Spectroscopy (CARS) and Stimulated Raman Spectroscopy (SRS) microscopy.

The picoEmerald system provides perfect temporal and spatial overlap of exit beams, is tunable between 700 ... 1950 nm, has 2 ps pulses with 10 cm-1 spectral width, is completely automated and fully computer controlled, and is extremely low-noise compared to all-fiber laser systems.

The picoEmerald system is suitable for Coherent Anti-Stokes Raman Spectroscopy (CARS), Stimulated Raman Spectroscopy (SRS), Second Harmonics Imaging (SHG), Pump-Probe Spectroscopy, SRS Microscopy of Vibrational Probes, and Surface Enhanced Hyper Raman Spectroscopy (SEHRS).

The picoEmerald system, in combination with APE’s SRS detection module and an inbuilt EOM (Electro-Optic Modulator), facilitates SRS microscopy with almost background-free imaging contrast. It also allows simple spectroscopic identification of the samples' fingerprint region based on Raman spectra databases.

The picoEmerald system is a turn-key system that combines user-friendly automation features and the utility of open-architecture light sources in a single box. Proper setup and calibration are essential for accurate and reproducible imaging, and the picoEmerald system provides both.
