ABSTRACT:
The invention relates to an electrooptical system mounted in a tunable laser cavity, made up of the association of passive and active birefringent components such as birefringent lenses (29) and electrooptical crystals (9), (10), (11) and (12) introducing a preset or adjustable optical-retardation as a function of the wavelength tuning range. The system is designed to be controlled by a small control voltage, and to tune the wavelength according to an arbitrary scanning law, with a tuning rate that can be high and with an adjustable emission line width.
