| titleOfInvention |
Laser amplification device with active control of beam quality and end bars |
| abstract |
The invention relates to a laser amplification device (200) comprising a doped amplifying plate (213) framed between two undoped bars (2141, 2142), together forming an amplification element (210). The upper and lower faces of the amplifying element are each covered by a temperature control system (230A, 230B). Each temperature control system (230A; 230B) comprises a cooling element (231A; 231B), and at least one heating element (232A; 232B) covering peripheral regions of the upper or lower face of the amplification element. The temperature control systems (230A; 230B) are substantially symmetrical to each other, in orthogonal symmetry with respect to a plane () parallel to the upper and lower faces of the amplifying plate. The invention makes it possible to maintain the optical quality of the laser beam to be amplified. |
