NLS-100-CL Tunable Narrow Linewidth Laser
Digital Laser Components
Integration of single-frequency PM fiber laser, large-bandwidth electro-optic modulator, driver and control circuit module
NLS-100-CL tunable narrow linewidth laser is a high-performance laser seed source designed for high-power laser systems. It integrates a single-frequency polarization-maintaining (PM) fiber laser, a large-bandwidth electro-optic phase modulator, and driver and control circuit modules. By applying a specific RF signal to the seed light via the electro-optic modulator, the NLS-100-CL tunable narrow linewidth laser successfully expands the spectral width from the kHz range to 100GHz. This effectively suppresses the Stimulated Brillouin Scattering (SBS) effect that can occur during high-power amplification, thereby boosting the output power.
Featuring a compact, integrated modular design, the tunable narrow linewidth laser offers high environmental adaptability. Its flexible software architecture supports real-time operational logging and fault diagnosis, and enables fine spectral tuning to optimize laser power output. The advanced phase modulation and spectrum optimization technology, combined with a high-speed FPGA DAC digital waveform generator and RF power amplification module, ensures precise control over the laser spectral signal. The NLS-100-CL is also suitable for coherent laser radar, high-speed phase modulation, and other high-energy laser applications.
