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. Use the BOOSTIK HP for:
- Optical length and frequency standards
- Quantum optics/computing & phenomena, such as 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
- Coherent communication
- Coherent beam combining

|Model||Standard Wavelength||Others Wavelengths||Output power||PM||Fast modulation|
|E15||1550.12 nm||1550 - 1570 nm||5, 10, or 15 W||Yes||Yes|
|Y10||1064.00 nm||1050 - 1090 nm||2, 5, 10, or 15 W||Yes||Yes|
The system is available with three types of ADJUSTIK seeders:
E15: This 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 stabilization, 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 (Polarization Maintaining) output ensures a fixed orientation of the polarization. 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 stabilize 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.
