Abstract
A laser gyro includes a semiconductor medium and assembled discrete elements, thus offering the possibility of producing large cavities for achieving the desired precision. More precisely, the laser gyro includes an optical ring cavity and a semiconductor amplifying medium with an external cavity having a vertical structure. The semiconductor amplifying medium which is used in reflection includes a stack of plane gain regions that are mutually parallel, and the dimensions of the cavity being substantially are larger than those of the amplifying medium.
