1.0 μm Industrial Single-Frequency Seed Laser

The core enabling technology of the company’s 1.0 μm laser is highly doped specialty fiber. Based on this specialty fiber material, a centimeter-scale single-frequency laser resonator is constructed, enabling kilohertz-level spectral linewidth output while effectively preventing mode hopping.

Through optimized circuit design, the laser achieves high frequency stability and low intensity noise. In addition, the resonator incorporates special temperature-control protection and shock- and vibration-resistant design, ensuring stable operation even under harsh external environmental conditions.
