Overview of the 2.0μm Wavelength Range

Fiber lasers operating in the 2.0μm region offer important advantages for industrial and scientific applications. This wavelength provides strong absorption in many materials, improved safety levels for certain environments, and compatibility with specialty mid-infrared photonic systems. Typical benefits include strong absorption in plastics, polymers, biological tissues, and various gases, suitability for processes that require controlled thermal influence, compatibility with hollow-core fibers and mid-IR components, and an improved eye-safety range compared to shorter wavelengths. These characteristics make the 2.0μm Industrial Single-Frequency Fiber Laser a valuable source where consistent performance, high beam quality, and narrow linewidth are essential.

What Defines a Single-Frequency Fiber Laser

A single-frequency fiber laser is engineered to operate on a single longitudinal mode, delivering a very narrow spectral line with minimal frequency drift. This behavior is achieved through advanced cavity design, precise stabilization mechanisms, and carefully optimized optical components that suppress mode hopping and competing modes. Core properties include extremely narrow linewidth, high spectral purity, long coherence length, minimal phase noise, and stable wavelength output over time. These characteristics support high-precision industrial, metrology, sensing, and scientific processes that cannot tolerate frequency instability. The 2.0μm Industrial Single-Frequency Fiber Laser is designed around these principles to deliver dependable optical performance for long-term use in demanding environments.

Key Features of the Laser

• Narrow linewidth operation that supports high-resolution sensing, coherent detection, and frequency-sensitive applications.
