ABSTRACT:
Methods and apparatus for improving the thermal performance of a slab laser pump cavity is provided. Absorbing regions placed on either side of an active lasing region through which the active region is pumped provides uniform heat dissipation across the width of the slab thereby providing one-dimensional heat flow perpendicular to the broad surfaces of the lasing medium and maintaining uniform lensing and birefringence. Foreshortened cold plates in thermal communication with the active lasing region also provide improved thermal performance by providing uniform one-dimensional heat flow perpendicular to the broad surfaces of the lasing slab. In addition, a compliant thermal interface of variable thickness is provided to also improve the distribution of heat flow. Further, cooling channels located within the cold plates are located to achieve uniform one-dimensional heat flow.
