The turn-key 19″ rack system includes control electronics and power supply and is ideal for laboratory work and experimental research e.g. in metrology.
You can choose the operating wavelength of the BOOSTIK HP system freely in the 1 or 1.5 µm range, and the excellent beam quality enables efficient frequency conversion (see figure below for examples).
The combination of ultra-low noise, narrow linewidth and high power output makes the Koheras BOOSTIK HP laser a highly versatile system for a long-range of applications such as optical length and frequency standards, Quantum optics / computing & phenomena (optical trapping, optical lattice, Bose-Einstein condensate (BEC), atom interferometer, squeezing), Nonlinear optics pump source (SHG, DFG, OPO), laser-based metrology (precision laser interferometry, spectroscopy), optical heterodyning and coherent communication and coherent beam combining.
Our aeroGUIDE fiber delivery patch cords is an excellent accessory for the BOOSTIK HP.

The system is available with three types of ADJUSTIK seeders:
E15: Is an Erbium doped fiber laser system for operation in the 1550-1570 nm wavelength range offering the lowest phase and frequency noise and narrowest linewidth of the entire laser portfolio. It is often deployed for interferometric sensor applications demanding 10s of kilometers of coherence length and ultra-high frequency stability.
Y10: Ytterbium-doped fiber laser system for operation in the 1050-1090 nm wavelength range with narrow linewidth and low intensity noise. This laser is commonly used for laser stabilisation, atomic physics, spectroscopy, fusion energy, general replacement of conventional Nd:YAG lasers, and many other applications.
Tuning and PM Options
- PM operation: The output of the fiber laser systems is per default Single Mode Fiber and PM (Polarisation Maintaing) output ensures a fixed orientation of the polarisation. This may be required whenever the laser output needs to be externally modulated or to be used with PM sensitive devices.
- Thermal wavelength tuning: The fiber laser systems are per default thermally tunable to enable the user to match and stabilise the laser at a certain wavelength.
- Piezo-electric wavelength tuning: Piezo tuning capability enables the user to frequency stabilize the laser wavelength to an external reference such as an atomic transition or interferometer to obtain even higher laser stability than provided by the thermal control.
Multi output
For applications where several outputs with the same wavelength are needed, the BOOSTIK HP system can be configured with up to 16 separate outputs. The multi-output configuration has the same low noise characteristics as the single output configuration and comes with the same narrow linewidth. For applications requiring multiple outputs at different wavelengths, please see the Koheras ACOUSTIK multi-channel systems.
