Want more details?

If you want more details about phase noise, spectral linewidth, frequency stability, or how to wavelength tune your Koheras laser, we have some application notes for you.

Laser phase noise is a frequency-domain view of the noise spectrum around the laser signal. Read more about phase noise in single-frequency lasers.

Spectral linewidth is a measure of the spectral content of the laser light. Read more about linewidth measurement methods.

The laser’s frequency stability is often described in terms of its spectral linewidth. However, this term lacks detail about the laser frequency noise, which is often critical in laser applications. Read the analysis of the laser frequency stability using beat-note measurement.

The wavelength of the laser is controlled by the temperature and strain of the DFB cavity. Learn how to tune your Koheras laser.
