摘要： A system includes a laser system having a master oscillator and a planar waveguide (PWG) amplifier having one or more laser diode pump arrays, a PWG pumphead, input optics, and output optics. The PWG pumphead is configured to receive a low-power optical beam from the master oscillator and generate a high-power optical beam. The PWG pumphead includes a laser gain medium, a cartridge, and a pumphead housing. The cartridge is configured to receive and retain the laser gain medium, and the cartridge includes one or more cooling channels configured to transport coolant in order to cool the laser gain medium. The pumphead housing is configured to receive and retain the cartridge, where the cartridge is removable from the housing.

摘要： 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.

摘要： A heat sink for cooling a laser gain medium includes a coolant channel, an inlet pore, an outlet pore, and a thermal optical interface (TOI) channel. The coolant channel is configured to receive a coolant for removing heat from the heat sink. The TOI channel is coupled to the coolant channel by the inlet pore and the outlet pore. The TOI channel is configured to receive a portion of the coolant through the inlet pore. The received portion forms an ultra-thin liquid TOI. The TOI channel is further configured to return a portion of the TOI through the outlet pore to the coolant channel.
