Abstract
A crystal oscillator including a laser light source for emitting a laser beam to an aligned quartz crystal coupled to an oscillator circuit by an optical feedback network. The optical feedback network is responsive to variations of misalignment of the laser beam with the crystal and correction signals generated for introduction back to the crystal to bring its frequency back to a constant standard frequency output.
