Abstract
Using the reflection of linearly polarized light from electrooptic material with an interdigital arrangement of electrodes, an electrically controllable diffraction (ECD) grating has been constructed for a He–Ne 3.39-μm laser. An intracavity modulation of 30% was obtained for a He–Ne 3.39-μm laser by setting the ECD grating inside the resonator with an applied voltage of 50 V.
