德国联邦物理技术研究院(PTB)研制的三种光学转换器可产生高端激光特性,可以极大地“活跃”现有的激光源。第一种为脉冲-连续波转换器,由束源产生的脉冲光可转变为连续光,且重复率也足够高;第二种为单频激光长期稳定器,这是一个脉泽-AOM模块,可以产生长期稳定的窄线宽参考光;第三种为基于AOM的自参考系统,无需额外的光源就可以测量频率梳和光纤激光器的最低相位噪声。三种最新研制的产品都 The three optical transducers developed by the German Federal Institute of Physics and Technology (PTB) produce high-end laser characteristics that can greatly “activate” existing laser sources. The first one is a pulse-continuous wave converter. The pulsed light generated by the beam source can be converted into continuous light and the repetition rate is also high enough. The second one is a single frequency laser long-term stabilizer, which is a pulse-AOM module , Which produces long-term, stable, narrow-line reference light. The third is an AOM-based self-reference system that measures the lowest phase noise of frequency combs and fiber lasers without the need for additional light sources. The three newly developed products are
