Model cOPA – Tunable Ultrafast Source for Microscopy & Spectroscopy
Unlock high-speed imaging and precision spectroscopy with Model cOPA, a three-beam ultrafast pulse source designed for MHz repetition rates in the one-micron wavelength range.
Optimized for Advanced Microscopy
Model cOPA is ideal for high-repetition-rate, four-wave mixing experiments, including 3D multimodal imaging of cells and tissue. All three beams are synchronized to less than 10 femtoseconds, ensuring exceptional temporal precision. With >100 nJ per pulse, it enables multimodal microspectroscopy followed by ablative tissue sectioning.
Advanced Tunability & Integration
Housed in a compact, dual-OPA system, Model cOPA is pumped by the high-stability IMPULSE™ fiber laser oscillator/amplifier for unmatched performance. Key features include:
- Independent Beam Tuning: Two OPAs deliver tunable wavelengths from 700–950 nm (signal) and 1130–1300 nm (idler)
- Residual Pump Light Output: >1 µJ at 1030 nm for additional experimental flexibility
- Motorized Electronic Tuning: Fully automated control for seamless wavelength adjustments
Designed for demanding applications in biomedical imaging, nonlinear optics, and high-speed spectroscopy, Model cOPA delivers powerful femtosecond pulses in a robust and user-friendly system.

Coherent Anti-Stokes Raman Scattering (CARS) & Nonlinear Microscopy with Femtosecond Lasers
cOPA enables advanced nonlinear microscopy techniques by delivering ultrashort pulses with high peak intensities, facilitating precise molecular imaging and spectroscopy.
Coherent Anti-Stokes Raman Scattering (CARS)
CARS microscopy utilizes nonlinear optical interactions to generate vibrational contrast without the need for fluorescent labeling. By synchronizing femtosecond pulses with molecular vibrational resonances, CARS enhances chemical specificity, making it a powerful tool for biomedical imaging, material characterization, and live-cell studies.
Other Nonlinear Microscopy Applications
