High Stability Narrow Linewidth Laser < 3kHz < 120dBc/Hz @1MHz - Leading China Suppliers & Factory Solutions
product description
Narrow Spectral Linewidth: Spectral linewidth <3kHz. The narrow linewidth concentrates the optical signal better in the frequency domain with higher spectral purity.
High Frequency Stability: Output laser frequency is stable, reducing issues like signal errors caused by frequency fluctuations. Widely used in fields requiring extremely high frequency stability, such as optical precision measurement and quantum precision measurement.
Strong Resistance to Dispersion: The narrow spectral linewidth helps reduce chromatic dispersion effects during fiber transmission. Can serve as a light source in fiber optic communication systems for high-speed data transmission and long-distance communication.
Compact & Lightweight Structure: Employs technologies like modular design to achieve narrow linewidth and high power output while maintaining small size for easy installation and use.
Strong Environmental Adaptability: Utilizes all-fiber design and fully sealed structure with strong anti-interference capability, enabling stable operation in various complex environments.
Good Modulation Characteristics: Products feature high modulation bandwidth and fast frequency modulation capabilities.
