Room Temperature Pulsed Broad Gain Laser for EC

Multimode lasers such the Room Temperature Continuous Wave Broad Gain Illuminator 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 Laser Kit (ECLK).

The following table lists the specific performance of the Broad Gain lasers shown in pulsed mode (expect BG-3.2-3.6 which operates CW). Only the tuning range and minimum power over the tuning range are part of the specification; the typical tuning curve is shown as an example and each laser will have a different tuning curve. The average power will vary over the tuning range and will will exceed the minimum value at its optimal point by a large amount but this maximum value can vary from laser to laser.

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!
