The spectrallinewidth narrowing is due to the common effect of squeezing and the radiation reservoir of the photonic band gap.
由于腔场压缩的出现与光子晶体带隙的共同作用，腔场发射谱的线宽变窄。

This type of devices are required to have high-speed, high quantum efficiency and ultra-narrow spectrallinewidth simultaneously.
这类器件需要同时具备高速、高量子效率、超窄光谱响应线宽的性能。

By using a laser cavity which consists of only two gratings and a resonant reflector, a N2-laser-pumped dye laser with a spectrallinewidth of 1.3 GHz has been made.
