ABSTRACT:
A quasi-planar monolithic unidirectional ring laser is disclosed including an Nd:YAG crystal shaped so that a ring formed therein has an out-of-plane angle of about 1.degree.. The reflection opposite the output-coupling point on the front face is off the rear face. This arrangement provides for a very low pumping threshold and reduced magnetic field requirements. The disclosed laser can be pumped with a semiconductor laser and yield single mode 1.319 .mu.m and 1.338 .mu.m outputs suitable for fiber optic communications.
