Abstract
Abstract A process for triggering a laser of a solid bar of active material, consisting of separating the rays emitted from the bar into two beams and rotating each of the beams in opposite directions so as to render them parallel with the optical axis of the cavity at the same time.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
95 words
The laser generator as claimed in claim 1, wherein a first set of reflecting surfaces separates the rays issuing from one end face of said rod into said two beams, another set of reflecting surfaces, operatively arranged with said first set of reflecting surfaces for injecting said beams into a portion of said rod end face which is on the opposite side of said plane from which they issued, and said means for subjecting each of said beams to a rotation in opposite directions comprises means for rotating at least one of said reflecting surfaces.
Claim 2
Dependent Claim
74 words
The laser generator as claimed in claim 1, wherein a pair of reflecting surfaces separates said rays issuing from one end face of said active rod into said two beams and wherein a circuit formed of four reflecting surfaces disposed in the form of a quadrilateral is operatively positioned with respect to said reflecting surfaces for receiving said beams and wherein one of said four surfaces constitutes a reflecting surface given n rotational movement.
Claim 3
Dependent Claim
66 words
The laser generator as claimed in claim 1, wherein a first reflecting surface deflects the rays issuing from a Portion of one end face of said active rod and three other reflecting surfaces are operatively disposed to directly inject said rays into another portion of said one end face, at least one of said other reflecting surfaces being formed by a reflecting member given rotational movement.
