    NLA-20-04 4-Channel Narrow Linewidth Low-Noise PM Fiber Amplifier

    Synchronously amplifying single-frequency narrow-linewidth laser, delivering 20W output power per channel (80W in total)

    The NLA-20-04 4-channel narrow linewidth PM fiber amplifier array is a core component for a new generation of low-noise fiber amplification systems. It features an integrated opto-electro-mechanical design with four independent, high-performance PM fiber amplifier channels. This PM fiber amplifier array module achieves a single-channel output power of 20W while maintaining a high beam quality of M²<1.1 and a polarization extinction ratio of >20dB. It also ensures extremely low phase noise and spectral broadening, providing a high-quality input for subsequent laser power amplification.

    Our tunable narrow linewidth laser seed source integrates a single-frequency PM fiber laser, a wide-bandwidth electro-optic phase modulator, and a driver circuit. By applying a specific RF signal to the single-frequency seed light via the modulator, the spectral width is successfully expanded from kHz to the 100GHz range, effectively suppressing the SBS effect that can occur during high-power amplification and thereby increasing the output power.
