Abstract

This paper discusses the effect of direct optical modulation of the radiation of a semiconductor laser and the possibility of creating a wave converter based on this effect. An experimental apparatus has been created, and the dependences of the modulation efficiency on the wavelength, the radiation power, and the duration of the action have been investigated. One hundred percent modulation has been achieved at wavelengths 405, 532, and 1064 nm, the requirements on the source power have been determined, and the temporal characteristics of the process have been investigated. A primary analysis is carried out, and the assumption that the given phenomenon has a thermooptical nature is proposed.
