  • K2-1000 1GHz 单腔双光梳激光器(1050, 525nm)

  • K2-1000 1GHz 单腔双光梳激光器(1050, 525nm)

    K2-1000 1GHz 单腔双光梳激光器，输出两台锁模飞秒激光器（光频梳），二者脉冲重复频率存在微小差值。时域上，系统可高速完成 1 ns量程内的光延迟快速扫描；频域上，通过外差探测，每一对光梳谱线均可产生拍频信号。凭借 GHz 级高重复频率，设备单根梳线可实现高输出功率。

    K2-1000采用创新的共腔架构，激光器在自由运转状态下即可实现超低噪声。两路光梳具有被动稳定特性，光强、时序与相位噪声高度相关。整机仅一套激光谐振腔，无需高速锁相电路与光放大模块，大幅简化传统双光梳、ASOPS 系统的复杂结构；体积小巧，综合性能优异。
