The PPCL700 tunable laser from Pure Photonics represents a cutting-edge solution in the realm of full-band tunable lasers. Designed with precision and versatility in mind, this laser is engineered to deliver exceptionally narrow linewidths of approximately 15 kHz. This feature, combined with significantly reduced low-frequency amplitude modulation (AM) and frequency modulation (FM) noise, makes it an ideal choice for high-performance applications.

The laser's ability to access any desired frequency set-point within the C-band or L-band further enhances its adaptability, offering output power settings ranging from as low as 7dBm to as high as 17dBm, depending on the specific requirements. Built upon the robust foundation of the Neophotonics telecom-grade tunable laser, the PPCL700 incorporates an advanced optical engine alongside a newly optimized electronics platform.

This integration results in superior noise performance and introduces a suite of additional control features, including sweeps, jumps, amplitude modulation, and frequency modulation. These enhancements are particularly beneficial for applications demanding high signal-to-noise ratios, such as sensing and test and measurement (T&M) environments. In its low-noise operational mode, the PPCL700 effectively disables its control loops, maintaining a stable and 'frozen' state. To ensure tunability and flexibility in this mode, Pure Photonics has developed specialized control schemes.

These schemes enable functionalities such as clean frequency sweeps, frequency modulation with a bandwidth of 100 kHz and an amplitude of up to 100 MHz, and amplitude modulation with a bandwidth of 1 MHz. Additional features include the ability to perform clean frequency jumps within two seconds, rapid full-range frequency scans, and integrated data acquisition capabilities. With these features, the PPCL700 stands out as a versatile and high-performance tool for a range of demanding applications.
