808 nm High Stability Single-Mode Pump Laser Source – Connet VENUS Series

The Connet VENUS series 808 nm high stability single-mode pump laser source is a fully integrated, turn-key laser system designed for demanding scientific and industrial applications. Built around a wavelength-stabilized single-mode semiconductor diode with FBG (fiber Bragg grating) stabilization, this source delivers a tightly controlled 808 nm output with excellent spectral purity and minimal wavelength drift. Its compact benchtop platform combines precision laser driving, temperature control, and user-friendly operation in one robust unit, making it ideal for both laboratory research and system integration.

This 808 nm pump laser source is optimized for use as a pump in fiber lasers and solid-state lasers, where stable and high-brightness single-mode output is critical for achieving consistent performance and long-term reliability. With typical output powers of 100 mW and 250 mW (other power levels available on request), the VENUS series provides sufficient pump power for a wide range of Yb-doped fiber and Nd-based solid-state gain media. The narrow spectral width (around 0.5 nm FWHM) and high side-mode suppression ratio help to enhance coupling efficiency into active fibers or crystals and reduce noise in precision photonics systems.

A high-definition LCD front panel offers direct, intuitive control of operating parameters, including continuously adjustable output power over a 0–100% range. Users can switch between coarse and fine power tuning modes to achieve rapid setup and precise power setpoints, which is especially useful in characterization measurements, laser alignment, and sensitivity studies. Output power stability on the order of ±0.5% (typical) after warm-up ensures that long-duration experiments, optical measurements, or system calibrations can be carried out with confidence in the pump’s contribution to overall system stability.

Internally, the VENUS 808 nm source employs advanced microprocessor-based control combined with high-precision ACC (automatic current control) and ATC (automatic temperature control) circuitry. This integrated control architecture maintains the laser diode at a stable operating temperature and drive current, minimizing wavelength and power fluctuations arising from environmental or load variations. Such a high level of control is comparable to other premium laboratory-grade pump laser sources and makes the unit well suited for fiber optic sensing, interferometry, nonlinear optics experiments, and other precision test and measurement tasks where repeatability and low drift are essential.

The optical output is delivered via single-mode fiber or polarization-maintaining fiber, allowing users to choose the configuration best suited to their polarization-sensitive or polarization-independent setups. A standard FC/APC connector minimizes back-reflections and ensures reliable interfacing with common fiber-based components and systems. With an output fiber length greater than 1 meter and optional connector configurations, the source can be easily integrated into existing benches, fiber networks, or OEM platforms without complex adaptation.

From an integration standpoint, the VENUS series 808 nm pump laser source is available both as a benchtop unit and as a module for OEM and system-level deployment. The modular version enables compact installation inside larger laser systems, measurement platforms, or fiber laser engines, while the benchtop model provides a ready-to-use solution for laboratory environments. The system offers suitable communication interfaces and optional control software to support remote computer control, automated test sequences, and integration into broader experimental or production control frameworks.

Designed to operate from a universal 100–240 VAC supply and to consume only about 10 W of power, the source is energy efficient and convenient to deploy in a variety of settings. Its operating temperature range of 0 to +50 °C and rugged construction support reliable use in typical laboratory and light industrial environments. Overall, the Connet VENUS 808 nm high stability single-mode pump laser source combines wavelength stability, power precision, and flexible packaging options, making it a powerful and versatile choice for fiber laser pumping, solid-state laser pumping, fiber optic sensing, and a broad spectrum of test, measurement, and scientific research applications.

Frequently Asked Questions

What is the Connet VENUS VLSS-808-B 808nm high stability single‑mode pump laser source used for?
The Connet VENUS VLSS‑808‑B is a high‑stability, single‑mode 808 nm pump laser source designed mainly for pumping fiber lasers and solid‑state lasers. Thanks to its narrow linewidth (≤0.5 nm FWHM), wavelength‑stabilized FBG design, and high output power (typically 100 mW or 250 mW), it is also widely used in fiber optic sensing, test and measurement setups, and general scientific research where a stable, precisely controlled 808 nm source is required.
What are the key technical specifications of the VLSS‑808‑B 808nm pump laser?
Key specifications include: - Center wavelength: 808 nm (typ. 808 nm, 803–813 nm range) - Output power: 100–250 mW (other custom levels on request) - Spectral width (FWHM): ≤0.5 nm - Side‑mode suppression ratio (SMSR): ≥20 dB - Output power stability: typically ±0.5% (≤±1% max, after warm‑up at 25 °C) - Output power tuning: 0–100%, with coarse and fine adjustment - Fiber type: SMF or PMF, length >1 m - Fiber connector: FC/APC (other connectors available on request) - Operating voltage: 100–240 VAC, power consumption ≈10 W max - Operating temperature: 0 to +50 °C; storage: –40 to +85 °C - Benchtop dimensions: 340 (L) × 240 (W) × 100 (H) mm
How is wavelength and output power stability achieved in this 808nm single‑mode pump laser?
The VLSS‑808‑B uses a single‑mode semiconductor laser diode with an integrated fiber Bragg grating (FBG) for wavelength stabilization, which keeps the emission tightly centered around 808 nm with minimal drift. A microprocessor‑based control system combines high‑precision ACC (automatic current control) and ATC/APC temperature and power control loops. These circuits regulate the drive current and diode temperature, compensating for environmental changes and aging, so the laser delivers highly stable output power (typically ±0.5% stability) and a narrow, stable spectrum over long operating times.
What package options and output power configurations are available for the VLSS‑808 series?
The VLSS‑808 series can be ordered as: - VLSS‑808‑B‑: Benchtop laser source (B = benchtop), with integrated LCD display and front‑panel controls. - VLSS‑808‑M‑: Module version (M = module), suitable for OEM and system integration. “PW” specifies the output power in mW, for example: - 100 → 100 mW nominal output - 250 → 250 mW nominal output Other output power levels within the design range can often be customized on request, similar to comparable 808 nm pump modules from other manufacturers used in fiber lasers and DPSS laser pumping.
Is the VLSS‑808‑B suitable for polarization‑sensitive or fiber‑optic sensing applications?
Yes. The VLSS‑808‑B can be configured with either standard single‑mode fiber (SMF) or polarization‑maintaining fiber (PMF), making it suitable for polarization‑sensitive applications such as certain interferometric or coherent fiber‑optic sensing schemes. The narrow spectral width, good SMSR, and high power stability are advantageous for fiber Bragg grating (FBG) interrogation, distributed sensing, and precision metrology where a stable 808 nm pump or probe source is needed.
How can I control and integrate the 808nm pump laser source into an automated system?
The benchtop VLSS‑808‑B offers local control via a high‑definition LCD display with continuously adjustable output power and real‑time display of current and voltage. For system integration and remote operation, Connet can provide communication interfaces and matching control software on request, allowing computer‑based control similar to other laboratory‑grade pump lasers. The module version (VLSS‑808‑M) is specifically designed for OEM integration, where the user can wire the control and monitoring signals directly into larger laser or measurement systems.
What fiber connector and customization options are available for the Connet 808nm pump laser?
By default, the VLSS‑808‑B uses an FC/APC fiber connector on a >1 m SMF or PMF pigtail, which is standard for low‑back‑reflection, single‑mode laser delivery at 808 nm. On request, other connector types commonly used in photonics—such as FC/PC, SC/APC, or customer‑specified connectors—can be supplied. In addition, output power level, fiber type (SMF vs PMF), packaging (benchtop vs module), and interface options can typically be tailored to match specific fiber laser, solid‑state laser pumping, or sensing system requirements.
