About the Ultra-Low Noise Fiber Laser Series

The Ultra-Low Noise Fiber Laser Series minimizes relative intensity noise (RIN) and phase noise for applications where even small fluctuations impact measurement accuracy. These systems deliver high OSNR, stable output power, and consistent long-term performance for both laboratory and industrial environments. They are designed as reliable building blocks for precision optical platforms that cannot tolerate instability or drift.

Series-Level Performance Advantages

• Extremely low relative intensity noise (RIN) across the operating bandwidth
• Stable frequency and power output with minimal drift over time
• Ultra-narrow linewidth options (Hz to kHz depending on model)
• High optical signal-to-noise ratio (OSNR)
• Consistent output over extended duty cycles and continuous operation

Technical Advantages of the Series

Noise suppression, precise cavity control, and advanced electronics maintain consistent intensity and spectral purity. These design choices directly benefit interferometry, coherent communications, spectroscopy, microwave photonics and sensitive sensing platforms. By combining advanced optical components with optimized electronic control, the series supports demanding system architectures that rely on ultra-stable optical sources.
