共振跃迁

当激光的强度和脉冲持续时间一定时，随着振动能级的升高，各级多光子共振跃迁的频率越来越小，说明了能级间隔越来越密，这与非谐振子的能级分布相吻合。

When the laser intensity and pulse duration are fixed , with the increase of vibrational quantum number , the multi-photon resonance transition frequency becomes smaller , which is consistent with the energy level distribution of non-harmonic oscillator .

非共振跃迁通常是通过强激光或多光子等光学非线性实现的。近年来，在生物超弱发光系统和光生物调节作用系统发现了低强度激光或单色光的非共振跃迁现象。

Non-resonant transition is often done by optical nonlinearity such as high-intensity laser irradiation or multi-photon , but it was recently found to be done by low-intensity laser irradiation or monochromatic light in biophoton emission systems and photobiomodulation systems .
