Abstract

Radiation field amplifier system for a radiation field comprising an amplifying unit (56) and a heat dissipation system (20) with one heat spreading element or several heat spreading elements (52,54), said one heat spreading element or at least one of said several heat spreading elements of said heat dissipation system is pressed with a contact surface within a contact area against said amplifying unit and said contact surface rises starting from a geometrical reference plane in direction towards said amplifying unit and a distance d between said contact surface and said geometrical reference plane attains its largest value within a central area, which is arranged inside said contact area and said distance d is smaller outside said central area than inside said central area. The transparent and isotropic heat spreading elements (52,54) may have a convex shape with the central and thickest part being pressed against the laser disk (56) to improve cooling of the laser amplifier. The pressure may be adjusted by a mount (146) with a spring (168).The pressure results in a birefringence of the heat spreader which can be controlled by the applied force. Compensation of thermal depolarisation by the amplifier is possible.
