<p>The secondary laser source of the invention comprises: at least a laser crystal (307), predisposed to receive in input a laser radiation and to emit in output a laser radiation having determined characteristics; an output optical unit (305), predisposed to receive the laser radiation emitted by the laser crystal (307) and to transmit to outside at least a laser radiation which exhibits a same wavelength as the laser radiation emitted by the laser crystal (307); a support (315) predisposed for supporting the laser crystal (307), which support (315) is made of a highly heat-conducting material; at least an active cooling element, located in contact with the support (315); a heat exchanger (318), struck by a cooling fluid, which is located in contact with the active cooling element (317). The invention also concerns a laser device comprising the secondary laser source.</p> |
