Abstract:
A laser source comprising:an active element for a laser source, said active element comprising an optical block which includes: an elongate rod, which comprises a doped matrix for absorbing a pump beam in order to amplify laser radiation propagating longitudinally along a longitudinal axis of the elongate rod; optical elements, which include a material having substantially the same optical index as said doped matrix, which are fixed respectively to faces of said rod, each of said optical elements having at least one input face for receiving the pump beam, the input face of each of said optical elements being formed at an inclined angle with respect to the longitudinal axis of the rod; and at least two reflection faces which interact with each other and the pump beam, at least one of the at least two reflection faces being formed at an inclined angle, with respect to the longitudinal axis of the rod, with an inclination direction opposite to that of said input face of a corresponding first one of said optical elements; and at least one pump source operable to emit a pump beam into said active element.
