| 摘 要： | 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633nm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。

| Abstract: | A monolithic scheme Ti： s femtosecond optical synthesizer was developed for absolute frequency measurement. After referencing the frepand fceofrequency 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 633 nm wavelength secondary standard,with a serial number NO. 02,was carried out. As a result,five different frequency peaks,c,d,e,g,h,were achieved. In this experiment,the relativity deviation of the value is about 10^-11. |
