• Wide Spectral Bandwidth & Flatness – Optimized ASE design with broad FWHM bandwidth and selectable spectral flatness:
  • Standard Flatness for general broadband applications and high total output power.
  • Gain‑Flattened Spectrum for applications requiring tighter spectral uniformity across the band (e.g., precise spectral characterization, sensing arrays).
• Single‑Mode or Polarization‑Maintaining Output – Two distinct models for optimal system integration:
  • VASS‑Yb‑B: Single‑mode output on SMF 6/125 µm, NA = 0.13 for low‑noise, high‑quality beams.
  • VASP‑Yb‑B: PM output on PM980, NA = 0.13 with > 17 dB polarization extinction ratio for polarization‑sensitive applications such as interferometry and coherent detection.
• High Isolation and Low Feedback Sensitivity – Integrated optical isolation up to 35 dB minimizes back‑reflections from downstream components, enhancing long‑term stability and protecting the internal ASE source.
• Coarse / Fine Power Tuning – Integrated digital control with coarse and fine output power adjustment allows users to precisely set and optimize the ASE power for different experiments or test setups.
• Benchtop, Highly Integrated Design – Compact benchtop unit (approx. 340 mm × 240 mm × 100 mm) with all‑fiber internal design for improved robustness, minimal alignment requirements, and plug‑and‑play operation.
• High‑Definition LCD Interface – Front‑panel high‑definition LCD displays current, voltage, and output power simultaneously, enabling real‑time monitoring and intuitive control without external instruments.
• Universal AC Power Input – Wide‑range input of 100–240 VAC for global compatibility in laboratory and production environments; optimized internal electronics for low power consumption even at maximum output power.
• Rugged, All‑Fiber Construction – Er/Yb‑doped all‑fiber configuration (no free‑space optics in the signal path) provides high stability, long‑term reliability, and immunity to vibration and misalignment, outperforming many free‑space based broadband sources.
• Stable Performance over Wide Temperature Range – Designed to operate reliably over typical laboratory and light industrial ambient conditions, with controlled internal temperature for consistent spectral characteristics and power output.
• Standard and Custom Fiber Connectors – Delivered with FC/APC output as standard to minimize back‑reflection; other connector types (FC/PC, SC/APC, etc.) and pigtail options can be supplied on request for easy integration into existing fiber networks.
• Long Output Fiber Pigtail – Supplied with a standard 1 m output fiber (other lengths available on request), providing flexibility for rack, bench, or optical table setups without the need for additional patch cords.
• Optimized for Precision Test & Measurement – High stability, low coherence, and broad bandwidth make this source ideal for:
  • Optical spectrum analysis and component characterization.
  • Passive device testing (filters, couplers, WDM components, isolators, etc.).
  • Optical time‑domain reflectometry (OTDR) calibration and verification.
  • Wavelength‑dependent loss (WDL) and polarization‑dependent loss (PDL) measurements.
