Abstract :
The optical feedback characteristics of a single mode He-Ne laser with a quartz crystal plate in the external cavity are studied. The fringe frequency of the laser system can be doubled when a quartz crystal plate is put by a certain angle between the crystalline axis and the beam in the crystal plate. Theory analysis shows that the birefringent effect of the quartz crystal plate and the laser beam´s second passing in the external cavity result in this phenomenon. The experimental results are in good agreement with the theory analysis. It can double the resolution of a self-mixing sensing system.
