  • 拉曼过程则牵涉到组成介质分子振荡激发态由于彼此相互作用光子会损失增加能量导致频率改变

    Raman processes involve light interacting with the vibrational excitations of molecules making up the medium; as a result, the photons of light lose or gain energy, which changes their frequency.

  • 目前波段的固态激光光源主要利用频率变换技术,通过频、受激频移的方法来获得

    Presently, an all-solid-state laser in this spectral range was obtained by frequency conversion, such as frequency-doubling, sum frequency, stimulated or Raman frequency-shifted.
