1550nm Nano-second Pulse Fiber Laser – DK-XS-DT-006-A/2

The DK-XS-DT-006-A/2 1550nm Nano-second Pulse Fiber Laser from DK Photonics is a high-performance, single-frequency fiber laser designed for advanced photonics applications. Utilizing a rare earth-doped fiber DFB (Distributed Feedback) laser cavity, this laser delivers a stable, single longitudinal mode output at 1550nm, making it an ideal choice for demanding environments where precision and reliability are paramount.

This fiber laser stands out for its ultra-narrow spectral linewidth of less than 3kHz and an exceptional side mode suppression ratio (SMSR) exceeding 60dB. Such characteristics ensure high spectral purity and minimal noise, which are critical for applications like high-power laser seeding, nonlinear optics experiments, and distributed fiber sensing. The all-fiber construction enhances robustness and longevity, reducing maintenance and ensuring consistent performance over extended periods.

Flexibility is a core advantage of the DK-XS-DT-006-A/2. Users can precisely adjust the pulse width (5–30ns), repetition frequency (1–100kHz), and peak output power (5–30W), allowing for tailored operation to meet specific experimental or industrial requirements. The laser is available in both desktop and compact module formats, catering to a wide range of integration needs, from laboratory setups to OEM system integration.

The device supports both SMF-28 and PM1550 Panda fiber types, ensuring compatibility with standard and polarization-maintaining fiber systems. With its robust power stability (≤±0.02dB over 15 minutes, ≤±0.05dB over 10 hours) and external trigger capability, the DK-XS-DT-006-A/2 is engineered for precision and repeatability. Its user-friendly interface—button control for desktop or RS232 for module—further simplifies operation and integration.

Designed to operate reliably in a wide temperature range (-5°C to +55°C) and humidity conditions (0–70%), this fiber laser is well-suited for both laboratory and field environments. Whether used as a high-power seed source or in advanced sensing and nonlinear optics, the DK-XS-DT-006-A/2 delivers the performance and versatility required by today’s photonics professionals.
