Single-frequency operation starts with the seed source
Optromix single-frequency systems use DFB fiber-laser seed sources. A distributed Bragg reflector in the fiber cavity supports single-longitudinal-mode emission, while amplification and frequency-conversion stages extend the available power and wavelength ranges.
The platform combines wavelength stability with thermal tuning and fast piezo tuning, allowing the source to be adjusted around the required operating wavelength.
