The DAYY Photonics Corporation introduces its advanced cooled Narrow Linewidth Laser (NLL), meticulously engineered for precision and stability. Encased in a robust 14-pin BTF package, this laser is part of the Optical Spectral Engine (OSE6) family. It is designed with a proprietary external cavity laser architecture that incorporates a built-in fiber Bragg grating. This innovative design ensures a single frequency emission, providing unparalleled stability in lasing wavelength, a remarkably narrow spectral linewidth, and an impressive side mode suppression ratio (SMSR).

The NLL is crafted to deliver exceptional performance, making it an ideal choice for applications requiring high precision and reliability. The laser's narrow linewidth, typically less than 200KHz, ensures a coherence length exceeding 0.5km, which is crucial for maintaining signal integrity over long distances. The device offers a range of wavelength options around 1260nm, 1383nm, 1550nm, 1648nm, 1653nm, and 1665nm, catering to diverse needs across various industries.

With a typical output power of up to 10mW in continuous wave (CW) mode and pulse power reaching up to 50mW, the NLL is engineered for high-performance applications. The laser's excellent relative intensity noise (RIN) of less than -140 dB/Hz for power levels above 10mW ensures minimal signal distortion, enhancing the quality and reliability of the output. Furthermore, the device supports direct intensity modulation up to 600Mbps, offering flexibility and adaptability for dynamic operational environments.

The DAYY Photonics NLL is Telcordia qualified, underscoring its durability and reliability in demanding conditions. The laser's wavelength stability is maintained at ±1 pm, with a typical polarization extinction ratio (PER) of 18 dB, ensuring consistent performance. The ability to specify the lasing wavelength precisely to 1nm and tune it thermally and via current adjustments provides users with exceptional control and customization capabilities.
