Polarization feedback laser stabilization

Patent · 28 September 1987

OSTI ID:6772423

Esherick, P; Owyoung, A

A system for locking two Nd:YAG laser oscillators includes an optical path for feeding the output of one laser into the other with different polarizations. Elliptical polarization is incorporated into the optical path so that the change in polarization that occurs when the frequencies coincide may be detected to provide a feedback signal to control one laser relative to the other. 4 figs.
