PROBLEM TO BE SOLVED: To provide an active element for laser source, which causes a pump beam to uniformly pass through an amplification medium for a long distance and a distance which can be controlled. SOLUTION: The active element for laser source is provided with a long rod having a doped generation source which absorbs the pump beam and can amplify a laser radiation propagating in a longitudinal direction, at least one input face for the pump beam, a first reflection face for the pump beam inclined with respect to the long axis of the rod and at least one second reflection face which conducts a mutual operation. At least one input face and the second reflection face are similarly inclined. |
