We first constructed a pair of optical frequency synthesizer(OFS) by phase-locking two CW near-infrared lasers to two optical frequency combs,respectively.Then, CW-THz wave was generated by photomixing output lights from OFSs with UTC-PD.Absolute frequency of the generated CW-THz wave was determined at uncertainty of 10-12by referencing to a microwave frequency standard. Furthermore,its output frequency was successfully tund over 1 GHZ.

首先通过将两个连续近红外激光器分别锁相到两个光频梳构造了一对光学频率合成器(OFS)，然后将OFSS的输出光与UTC-PD进行光电混合产生CW-THz波，并参照微波频率标准在10-12的不确定度下确定了产生的CW-THz波的绝对频率。此外，其输出频率成功地超过了1 GHz。
