K2-ASOPS 异步光学采样系统

泵浦 - 探测（ASOPS 异步光学采样）测量的理想设备，低重频单腔双光梳激光器。


核心参数

两路空间分离脉冲序列，单路输出功率＞1.5 瓦

脉冲宽度＜250 飞秒

亚周期级相对时间抖动

超低相对强度噪声

基模高斯光束输出

重复频率差可调，且长期稳定

设备结构高度紧凑

全自动交钥匙设备，可 7×24 小时连续运行


产品说明

单台K2-ASOPS输出两路锁模飞秒激光器（光学频率梳），二者脉冲重复频率存在微小差值。时域上，设备可高速扫描最大 16ns的光程差；频域上，通过外差探测，每一对梳齿均可产生拍频信号。K2-ASOPS采用创新的共腔结构，仅依靠自由运转即可实现超低噪声。两套光梳具备被动自稳定特性，两路光梳的强度噪声、时序抖动与相位噪声高度关联。整机仅配备单一激光腔，无需高速锁相电路与光放大模块，大幅简化传统双光梳、异步光学采样设备的复杂结构，同时兼具体积小巧、性能优异的优势。
