COSMO: Comb Offset Stabilization Module
Self-referencing made simple!
The Octave Photonics Comb Offset Stabilization Module (COSMO) provides a compact and convenient solution for the f-2f self-referencing of a laser frequency comb. Additionally, the COSMO allows the carrier-envelope-offset (CEO) frequency to be detected with exceptionally low pulse energies, enabling lower power consumption or higher repetition rates.
The COSMO simplifies the f-2f self-referencing process. The COSMO connects to the laser with a fiber connector (FC/APC or similar) and provides an electrical output that can be connected to the comb stabilization electronics.
Standard features:
Input wavelength: ~1560 nm
Minimum pulse energy: <200 pJ
Repetition rate: 50 MHz to 2 GHz
Input: PM1550 fiber, FC/APC connector
Output: SMA connector
Dimensions: 57x35x17 mm
CEO Signal-to-noise ratio: >35 dB
