为了进行光频的绝对测量实验研究，本课题组研制了基于MgO： PPLN晶体的“单块”结构飞秒激光频率梳，在利用稳频电路将重复频率frep和载波包络相移频率fceo同时锁定到氢原子钟上后，其光频齿的频率稳定度同步于氢原子钟。利用该高稳定度“单块”结构钛宝石飞秒激光频率梳对编号为NO．02的633 nm激光波长国家副基准装置进行了激光频率的绝对测量实验，得到了5个峰的测量结果，各光频测量结果相对偏差为10-11量级。

A monolithic scheme Ti: s femtosecond optical synthesizer was developed for absolute frequency measurement. After referencing the frep and fceo frequency to an H atomic clock, the frequency stability of the single optical tooth is synchronous to the atomic frequency reference. An absolute optical frequency measurement of the 633nm wavelength secondary standard, with a serial number NO. 02, was carried out. As a re-sult, five different frequency peaks, c, d, e, g, h, were achieved. In this experiment, the relativity deviation of the value is about 10 -11.
