Femtoline Laser Output Couplers SKU: 045-0175
• Low Group Delay Dispersion (GDD) An output is a partially reflecting dielectric mirror used in a laser cavity. It trasmits a part of the circulating intracavity power for generating a useful output from the laser. A low transmission output coupler leads to low laser…
