980 nm High-Stability Single-Mode Pump Laser Source – BENCHTOP VENUS / VLSS-980-B Series

The Connet VENUS / VLSS-980-B series is a high‑stability, 980 nm single‑mode pump laser source designed specifically for demanding fiber‑optic research and amplifier pumping applications. Built around one or two high‑power, wavelength‑stabilized laser diodes with fiber Bragg grating (FBG) locking in the 980 nm band, this benchtop source typically operates near 975 nm and delivers output powers configurable up to 1400 mW. Its robust internal design combines advanced automatic temperature control (ATC), automatic power control (APC), optimized thermal management, and carefully engineered optomechanics to ensure outstanding power stability and long‑term reliability in both laboratory and system integration environments.

The output of the VENUS / VLSS-980-B series is available through high‑quality single‑mode or polarization‑maintaining (PM) fiber, terminated with an FC/APC connector to minimize back‑reflection into the pump diode. A high‑definition LCD on the front panel provides clear, real‑time readout of output power and operating status, while intuitive controls enable easy adjustment of the output power from 0 to 100% with coarse and fine tuning modes. This plug‑and‑play architecture allows users to quickly set up and operate the laser source without complex alignment or software configuration, making it ideal for daily experimental work, device characterization, and system testing.

For applications such as erbium‑doped fiber amplifiers (EDFA), erbium‑ytterbium‑doped fiber amplifiers (EYDFA), and ytterbium‑doped fiber amplifiers, pump diode protection is critical due to amplified spontaneous emission (ASE) and potentially harmful back‑reflected light. The VENUS / VLSS-980-B series integrates dedicated ASE feedback protection and optional enhanced pump‑protection schemes tailored to different fiber laser and amplifier architectures. This protection strategy, combined with an output isolation level typically around 30 dB (for ASE feedback), helps minimize the risk of pump failure and extends the operational lifetime of the device compared with conventional 980 nm pump modules lacking such safeguards.

With a narrow spectral width (typically around 0.5 nm FWHM) and a side‑mode suppression ratio on the order of 20 dB, the source provides spectrally clean pump light well suited to high‑gain, low‑noise amplifier designs. The high power stability (on the order of 1% under nominal lab conditions after warm‑up) supports applications where gain fluctuations directly impact system performance, such as high‑power and low‑noise EDFAs, mode‑locked fiber lasers in the 1.0 μm and 1.5 μm bands, and precision test and measurement setups. Typical output power configurations, such as 400 mW, 600 mW, or other custom levels within the 90–1400 mW range, can be specified to match the requirements of new designs or to retrofit existing amplifier platforms.

From an integration standpoint, the compact benchtop housing (approximately 340 mm × 240 mm × 100 mm) and universal 100–240 VAC input make the VENUS / VLSS-980-B series straightforward to deploy in standard optical laboratories and 19‑inch rack environments. The system is designed to operate reliably over a 0 to +50 °C ambient temperature range, with storage down to –40 °C, supporting both permanent setups and mobile or field‑lab configurations. For automated test benches or remote operation, an RS‑232 communication interface and control software can be provided on request, enabling computer‑based monitoring, power control, and scripting within larger photonics test systems.

In comparison with typical 980 nm pump laser sources used for EDFA and fiber‑laser pumping worldwide, the VENUS / VLSS-980-B series combines high output power, narrow linewidth, FBG‑locked wavelength, integrated ASE/back‑reflection protection, and user‑friendly desktop operation in a single package. This positions it as a versatile tool for researchers and engineers who need a stable, configurable, and reliable 980 nm pump for amplifier development, mode‑locked laser seeding, and other advanced fiber‑optic experiments where stability, spectral purity, and operational safety of the pump source are essential.
