KOHERAS ADJUSTER

X15: Erbium-doped fiber laser enabling output in the wavelength range 1535-1580 nm (1545-1565 nm for HP version). 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 (1545-1565 nm for HP version). 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 length.

Y10: Ytterbium-doped fiber laser enabling output in the wavelength range 1030-1120 nm (1060-1075 nm for HP version) with narrow spectral linewidth 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.

T20 HP: The Thulium-doped T20 HP laser has been designed to excite barium ions at 1762.17 nm. It is mainly used for quantum applications such as quantum sensing, atom cooling, qubit manipulation, etc.

Functions

• PM output. This may be required whenever the laser output needs to 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.
