The two photons go off together as coherentradiation .
这两个光子一起发射出去，形成相干辐射。

Therefore, ZGP has been approved to be an ideal nonlinear laser crystals for generating tunable mid-infrared coherentradiation.
证实了ZGP晶体是一种可以产生可调谐中红外输出的较为理想的非线性光学晶体。

The generation of the coherentradiation in a conventional laser results from the transitions between the quantum states of the electrons, which are attached to the atoms.
