A laser probe for electrically steering a light beam includes a tubular-shaped housing, an optical waveguide, and a beam steering cell. The optical waveguide is disposed within an interior region of the housing and is configured to emit a light beam travelling in a first direction. The beam steering cell is disposed within the housing and comprises an electro-optical (EO) material. The beam steering cell is configured to receive one or more voltages and electrically steer the light beam with the OE material to a second direction. The EO element has a shape of varying thickness such that a first portion of the light beam passes through a portion of EO element having a greater thickness than a second portion of the EO element passed through by a second portion of the light beam. The laser probe may be a directional laser probe or a multi-spot laser probe. |
