# 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 Laser Kit (ECLK).

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.

Laser | Tuning from | Tuning to | Avg. Power at optimum frequency | Typical tuning curve |
---|---|---|---|---|

BG-4.3-5 | ## <1970 cm-1 | ## >2270 cm-1 | >2 mW | |

BG-5-6 | ## <1655 cm-1 | ## >1860 cm-1 | >10 mW | |

BG-6-7 | ## <1380 cm-1 | ## >1540 cm-1 | >1mW | |

BG-7-9 | ## <1155 cm-1 | ## >1390 cm-1 | >6mW | |

BG-7.7-10.2 | ## <1030 cm-1 | ## >1300 cm-1 | >12mW | |

BG-10-12 | ## <880 cm-1 | ## >1005 cm-1 | >1mW | |

BG-11-14 | ## <800 cm-1 | ## >885 cm-1 | >1mW |

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!
