The Koheras BOOSTIK fiber amplifier extends the output power of the Koheras BASIK seed laser while preserving the ultra-low noise and narrow linewidth operation.
Designed to preserve the ultra-low phase noise and low RIN of the Koheras seed lasers it is the ideal choice for noise-sensitive applications in high precision metrology, laser cooling, quantum physics and sensing, and various scientific applications.
The amplifier is designed for operation in the 1545-1565 nm range. It is fully compatible with the BASIK E15 and C15 seed laser models and has an optical output power up to 2 W.
The amplifiers are designed as compact line cards for the Koheras ACOUSTIK multi-wavelength system seeded by our range of ultra-low phase noise single-frequency lasers: E15, X15, and C15. This offers high flexibility and freedom to choose the specific wavelengths and power levels required for each individual user application.
Laser and amplifier wavelengths can be changed to accommodate the system to future user needs which makes the system highly versatile and upgradeable. The amplifier module occupies two slots in the Koheras ACOUSTIK system.
- Designed for narrow linewidth operation
- Up to 2 W output
- Plug and Play
- Robust and maintenance-free
- Multi-channel system or stand-alone
Polarization-maintaining fiber output
The Koheras BOOSTIK amplifier is provided with standard single-mode
fiber or a polarization-maintaining option.
For applications that require low RIN (Relative Intensity Noise), the
Koheras BOOSTIK amplifier can optionally be provided with up to
20 dB reduction in RIN level. For more information, please refer to
the optical product specifications.
