3-Colour Picosecond Laser



  • 3-Colour Picosecond Laser (450, 515, 640 nm)
  • Compact, stand alone, affordable
  • Pulsed and CW operation, fast CW switching
  • Suitable for measuring Fluorescence lifetime (ns) and Photoluminescence lifetime (µs-ms)
  • Triggerable internally and externally, up to 200 MHz
  • Fully computer controlled


Prima is a solution for researchers who:

  • Need more than one wavelength
  • Don’t have space in the lab
  • Measure a short decay time (ns) and a long one (µs-ms)
  • Deal with materials that have a poor luminescence quantum yield
  • Would like to avoid daily alignment and laser maintenance


The Prima 3-Colour Picosecond Laser can be used for various applications.

It is the ideal tool for covering most of your daily needs when it comes to exciting a broad range of samples for tasks such as:

  • Materials Science and chemical research
  • Life Science
  • Photoluminescence lifetime and quantum yield measurements
  • Fluorescence lifetime measurements
  • Time-resolved microscopy and single molecule detection (FLIM, FRET, PIE-FRET, FCS)
  • Pulsed Interleaved Excitation (PIE)
  • Detector testing
  • Antibunching
  • LiDAR


Red, green, and blue: the three most utilised wavelengths
Each colour can be generated individually, one at a time. These wavelengths are the three most commonly used in materials science, chemistry and life science for routine excitation in spectroscopy or microscopy applications to study a wide range of samples, including novel nanomaterials or quantum dots.

Pulsed, CW, and fast switched emission modes
Prima offers full flexibility, enabling you to perform time-resolved or steady-state measurements. Fast CW switching is a smart solution for measuring longer lifetimes in the µs to ms range. It is especially efficient for materials with a poor luminescence quantum yield. The pulsed mode can be driven either internally at selected repetition rates between 100 Hz and 200 MHz or externally, with rates ranging from single shot up to 200 MHz. Moreover, you can combine Prima with other laser diode heads to create even more sophisticated excitation patterns, such as bursts, Pulse Interleaved Excitation (PIE), or Alternative Laser Excitation (ALEX).
