Stand-Alone Gain-Switched Picosecond Lasers


3-Color Gain-Switched Picosecond Laser

  • NEW: three colors can be selected from 405, 450, 488, 515, 640 nm
  • Compact, stand-alone
  • 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
  • SM-PM fiber-coupling is available for combination 450, 515, 640 nm with 35% coupling efficiency

 "We can perform about 90% of our spectroscopy experiments with the three excitation wavelengths provided by Prima. Prima can greatly simplify our optical set-up thanks to its small size and fiber output, which facilitates its use."

Dr. Alexandre Fürstenberg 
Group leader and senior lecturer (MER), University of Geneva

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  


Prima provides the 3 most commonly used in materials science, chemistry and life scienceRed, green, and blue: the three most utilized 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).
