External Cavity Lasers
Multimode lasers such the Fabry-Perot lasers and Broad Gain Illuminators can be used in an External Cavity to provide single-mode operation with a broad tunability. You can read more here about Alpes’ External Cavity Development Kit.
The following Broad Gain lasers are compatible with the ECLK and will allow a tuning range as shown in the following table. They can also be supplied as chip on submount.

Furthermore, standard Fabry-Perot lasers with a narrower gain can also be compatible with the ECLK. You can see here a small subset of the performances available. For performances at other wavelengths, write to us to request testing!
