Abstract
A laser source (1) includes a pumping system (2) and an active element (3) which comprises a doped elongate rod (4) and at least one optical block (5, 6) for guiding the pump rays (F) of at least one pump beam toward the rod (4). The pumping system (2) generates a number of parallel pump rays (F). The entry face (5A, 6A) of the optical block (5, 6) is inclined to the longitudinal axis (X—X) of the rod (4) and is not orthogonal to the pump rays (F) in order to deflect the pump rays (F) by refraction so as to transmit them toward the rod (4), and the inclination of the entry face (5A, 6A) is such that the pump rays (F) reach the bar (4) so as to be distributed over its entire length.
