Picosecond Laser Tunable

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 nm to 990 nm (Signal) and 1080 nm 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.

The key-facts of the picoEmerald are:

  • Wavelength 1 IR beam 1032 nm
  • Wavelength 2 tunable 700 nm … 990 nm
  • Wavelength 3 tunable 1080 nm … 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

picoEmerald provides ultra-short picosecond laser pulses with a pulse repetition rate of 80 MHz.

Faster Achievements with a Single Output Port

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.

Outstanding Reliability

All optical modules of the tunable picosecond laser picoEmerald were optimized by finite element analysis and mechanical stability algorithms (misalignment stability optimization). This ensures maximum mechanical stability. In addition, active cavity control continuously maximizes the efficiency of the high-performance picosecond laser oscillator and the integrated optical parametric oscillator. The picoEmerald is supplied with an internal closed-loop chiller to ensure stable operation. A panel PC with pre-installed control software and a user interface are part of the delivery. The picoEmerald is designed to be a “hands-free” unit. It is not necessary for the user to interact with the laser except via the software interface.

Narrow Bandwidth with Picosecond Pulses

picoEmerald allows for the efficient generation of tunable narrow-bandwidth pulses. The narrow bandwidth of the picosecond laser compared to femtosecond laser is beneficial to perform resonance-specific and vibrational mode-specific excitation experiments. This is due to the reason that most vibrational bands (or cross-sections) in the spectral region of interest tend to have only a few wave numbers of bandwidth. With a pulse duration of 2 ps, picoEmerald is therefore ideally suited for many spectroscopy applications and experiments.

If even narrower bandwidths are required, the picoEmerald can be combined with a spectrum slicer. The main task of the pulseSlicer from APE is to cut out a very narrow spectral part of the picosecond laser pulse. This function is comparable to a monochromator or bandpass filter.


Several options regarding the configuration of the picosecond laser are available:

  • A power version of > 700 mW (at 1032 nm)
  • An elevated power version of > 2 W (at 1032 nm)
  • A long pulse version with 3.5 ps instead of 2 ps
  • An elevated power version of > 2 W (at 1032 nm) with an additional IR output port > 4 W (at 1032 nm)


picoEmerald provides fully automated temporal- and spatial-overlapping ultra-short pulse trains, perfectly suited for CARS & SRS.

Quantum Dot Single-Photon Generation

The combination of the tunable picosecond laser picoEmerald and the spectrum slicer (laser monochomator) pulseSlicer supports customers in the field of quantum research.
