| Zusammenfassung: | A laser gyro of the present invention includes laser light excitation means (a semiconductor laser device ) that excites first and second laser lights propagating in the opposite directions to each other in a circular ring-shaped path (an optical path ), coupling means (optical waveguides and ) for superimposing the first and the second laser lights, and a photodetector for observing an interference signal generated by the superimposed first and second laser lights. |
