ATLAS 1550 – C-band wavelength-tunable laser
The ATLAS 1550 is a C-band wavelength-tunable narrow linewidth laser centered around 1550 nm. The laser is well-suited for telecom applications, optical component testing, could be used as a lab tool or in advanced photonics research such as quantum key distribution (QKD). We offer two versions: the ATLAS1550-100, with a broad 100 nm tuning range, and the ATLAS1550-50, with a 50 nm tuning range, delivering slightly higher output power at a cost-effective price point.

ATLAS 1550-100 Specifications
| Parameter | Specified Values |

ATLAS Adapter
The base module comes equipped with a standard DE9 connector. We offer an add-on module featuring connectors for power, communication (USB-C) and trigger signals (SMA).
To meet laser safety standards, this module adds key control and a remote interlock connector.
Intuitive Software for Seamless Laser Operation
For intuitive operation and control, we provide a software interface which includes a graphical user interface (GUI) for straightforward wavelength setting and tuning, along with a Python library for advanced laser control functions.
