Abstract
Second‐harmonic generation (λ = 5.3 μ) is observed when dc fields and CO2 laser beams are applied simultaneously to narrow band‐gap semiconductors. The nonlinear mechanism responsible for the dc‐induced second harmonic is shown to be a mobile‐carrier effect, and is ascribed to the nonparabolicity of the conduction bands. The possible application of this effect to the modulation of optical beams is indicated.Keywords
