An analogy was established between Raman scattering in crystals and the conversion of photons into axions and vice versa. The conditions of light emission observation in experiments such as “Light Shining Through Wall” performed in recent years are analyzed. It is shown that the intensity of secondary light emission resulting from the “conversion-reconversion” process can be significantly increased by employment of the stimulated emission instead of spontaneous one, using intense (∼10
