Unico 1-Color Gain-Switched Picosecond Laser

Compact, stand-alone picosecond laser delivering precise and versatile excitation for time-resolved fluorescence and photoluminescence applications. 375–640 nm.

CLEAN PULSES. COMPACT DESIGN. CONFIDENT RESULTS.


Key Benefits

  • Improved time-resolved data quality — clean, high-quality pulses with excellent temporal stability
  • Easy integration & operation — fully integrated driver, no external components needed
  • Stable long-term performance — consistent output across all configurations
  • Compact footprint for any setup — minimal footprint for effortless integration
  • Reliable day-to-day measurements — proven gain-switching technology

Designed for Time-Resolved Spectroscopy and Imaging

Built on PicoQuant’s proven gain-switching technology, Unico delivers clean, high-quality pulses with excellent temporal stability, making it an ideal choice for time-resolved spectroscopy and imaging, including TRPL, FLIM, FRET, and related methods. Its fully integrated design eliminates the need for external drivers, enabling effortless integration into any experimental setup while maintaining a minimal footprint. With several available wavelengths and consistent performance across all configurations, Unico provides a versatile excitation source for demanding life science and materials science workflows.


Fibre Coupling Option

Unico can be delivered with a single-mode fibre output that offers efficient and stable beam delivery. Typical coupling efficiencies are above 40% and provide a clean, well-defined signal suitable for fibre-based experiments. Each unit is aligned before shipment to ensure consistent performance at the fibre connec
