The 1480nm Fiber Laser from DK Photonics is a high-performance, single-wavelength pump source specifically engineered for fiber laser and amplifier systems. Built around a high-reliability butterfly semiconductor laser chip, this source delivers stable, high-output power at 1480 nm with excellent spectral purity. A carefully optimized drive circuit and precision TEC (thermoelectric cooler) control work together to maintain constant operating conditions, ensuring consistent power and wavelength stability even over long operating periods. This makes the unit particularly suitable for demanding laboratory, industrial, and telecom environments where repeatable performance is critical.

Designed as a versatile pump laser, the 1480nm Fiber Laser is ideal for use in erbium-doped fiber amplifiers (EDFA), fiber laser pumping stages, and advanced nonlinear optics experiments. Typical output power options of 200 mW, 400 mW, 500 mW, and 800 mW give system designers flexibility to match pump power to their specific gain and noise figure requirements. With a center wavelength of 1480 ± 10 nm and very low short-term and long-term power drift (≤ ±0.02 dB over 15 minutes and ≤ ±0.05 dB over 8 hours), the laser provides the stability needed for high-gain, low-noise optical amplification and precise research applications.

To support integration into a wide range of optical architectures, the laser can be supplied with either standard single-mode SMF‑28e fiber or PM1550 panda polarization-maintaining fiber. This allows straightforward use in both conventional telecom-style systems and polarization-sensitive setups, such as coherent detection schemes or nonlinear optics experiments that require a defined polarization state. The standard FC/APC connector interface facilitates low-back-reflection coupling and easy connection to existing fiber networks, pump combiners, and experimental testbeds.

The 1480nm Fiber Laser is available in both compact module and convenient desktop configurations to suit different deployment scenarios. The module version is optimized for OEM integration and system-level design, featuring RS232 control for remote communication and compact dimensions of 125 mm (W) × 150 mm (D) × 20 mm (H). It operates from a 5 V DC power supply with power consumption under 15 W, making it an efficient choice for space- and power-constrained platforms. For laboratory and R&D use, the desktop version provides an intuitive front-panel button control interface, universal 100–240 V AC power input, and a robust 260 mm (W) × 280 mm (D) × 120 mm (H) enclosure that is well-suited for benchtop setups and continuous operation.

Engineered for reliability as well as performance, this 1480 nm source is specified for an operating temperature range of −5 °C to +55 °C and a humidity range of 0–70%. The integrated thermal management and carefully selected components help to minimize wavelength drift and avoid power fluctuations that can adversely affect system gain, bit error rates, or measurement accuracy. Compared with many generic pump modules on the market, the DK Photonics design emphasizes strong power and spectral stability, making it a solid choice for modern DWDM EDFA systems, high-power fiber laser pumping chains, and precision nonlinear optics research where long-term repeatability and low maintenance are paramount.

With its combination of high output power, tightly controlled wavelength, low noise, and flexible packaging, the 1480nm Fiber Laser offers a robust solution for engineers and researchers seeking a dependable pump source. Whether it is deployed to boost optical communication links, seed or pump specialty fiber lasers, or drive nonlinear phenomena in advanced photonics laboratories, this laser series provides a balanced mix of performance, reliability, and ease of integration that aligns well with current industry standards and expectations for 1480 nm pump technology.
