1.0 μm High-Reliability Single-Frequency Seed Laser

The 1.0 μm single-frequency seed laser is a laser with fully independent intellectual property rights and performance at an internationally advanced level. It features an ultra-compact DBR short-cavity design, effectively eliminating mode hopping and achieving ultra-narrow linewidth single longitudinal mode output.

The core technology is highly doped specialty fiber, which forms a centimeter-scale single-frequency laser resonator, enabling kilohertz-level spectral linewidth output and preventing mode hopping. Optimized circuit design ensures high frequency stability and low intensity noise. Additionally, the resonator incorporates special temperature-control protection and anti-shock vibration design, ensuring stable operation even under harsh environmental conditions.
