X15: Erbium-doped fiber laser enabling output in the wavelength range 1535-1580 nm. The X15 features extremely low phase noise, low intensity noise and a very narrow linewidth (<0.1 kHz). It is often used for interferometric sensor applications requiring tens of kilometers of coherence length.
E15: Erbium-doped fibre laser enabling output in the wavelength range 1535-1580 nm. The E15 features very low phase noise, low intensity noise and a very narrow linewidth (<0.1 kHz). It is often used for interferometric sensor applications requiring tens of kilometres of coherence.
Y10: Ytterbium-doped fibre laser enabling output in the 1030-1120 nm wavelength range with a narrow spectral line and low intensity noise. This laser is commonly used for laser stabilization, atomic physics/metrology, spectroscopy, fusion energy, replacement of conventional Nd:YAG lasers, and many other applications.
Optional features
- PM Output. This may be required whenever the laser output must be externally modulated or frequency converted.
- Temperature Frequency Tuning: Koheras lasers are equipped with a basic output frequency (wavelength) temperature tuning capability, allowing the laser to be stabilized to specific wavelengths within the available range.
- This feature can be useful for applications requiring higher wavelength stability than that provided by a free-running laser. The feature allows the output wavelength of the laser to be "locked" to an external reference source such as an atomic transition level or interferometer, for example. Tuning is handled by a piezo element.
