APE picoEmerald Picosecond Tunable Laser

One-box with multi-colour output


The picosecond laser picoEmerald emits ultra-short pulses with a duration of 2 picoseconds (other durations possible). The wavelength tuning of the ps laser is fully automated across a tuning range of 700 to 990 nm (Signal) and 1080 to 1950 nm (Idler). The fundamental beam at 1032 nm is also available. A wavelength scan / sweep function for fast spectra acquisition over certain specific wavelengths is included.



  • Wavelength 1 IR beam 1032 nm
  • Wavelength 2 tunable 700 … 990 nm
  • Wavelength 3 tunable 1080 … 1950 nm
  • Temporal and spatial overlap of the output wavelengths
  • Integrated time-delay between the wavelengths
  • A common output port for all beams
  • Fully automated wavelength tuning
  • EOM optionally integrated

With the picosecond laser picoEmerald, Idler and Signal beams and the IR beam (1 µm from the pump laser) are designed to come from one and the same output. They are perfectly overlapping in space and time. Therefore, there is no need for the user to use additional optics to guide the different beams into one location.


Users often want to use the entire wavelength range provided by the IR beam and the Signal and Idler output. Some applications, such as Coherent Raman Spectroscopy, even require the different beams being spatially and temporally overlapped. The difficulty with most laser systems is that IR, Signal and Idler beam come from different outputs. The different beams can therefore not easily be coupled into one and the same experiment. With the common single output port of the picoEmerald, the user has the certainty and comfort of not having to create their own beam path for the individual beams.


The picoEmerald has an integrated delay management (GDD dispersion compensated output). This allows the perfect adjustment of the time delay between the IR and the Signal beam even for external optics, in order to deal with dispersion differences at the different wavelengths. Each time the picoEmerald picosecond laser is tuned to a new Signal wavelength the delay of the IR beam is adjusted automatically for achieving a temporal overlap between Signal and IR pulse either at the output port or at an external experiment position.
