COMET-1550 Narrow Linewidth Laser Module

The COMET‑1550 is a narrow‑linewidth tunable laser based on a hybrid integrated external‑cavity structure. Employing advanced photonic integrated circuit (PIC) technology, it offers significant advantages, chief among them: ultra‑narrow linewidth, broadband tuning capability, and compact form factor. The COMET‑1550 module consists of a butterfly‑packaged laser mounted in a dedicated tunable laser controller optimized for this model, together with calibration elements and control software. The controller integrates a current driver, heater driver, and temperature controller for precise laser regulation. It also provides a software interface that allows users to flexibly adjust various laser parameters via a graphical user interface (GUI). In addition, an API serial command list is provided to facilitate secondary development and system integration.
