BIREFRINGENCE COUPLED HIGH AVERAGE POWER LASER

摘要

A high average power laser which has a rod (1) arranged in a cavity between two reflectors (2) and includes in the cavity on the axis of the laser rod at least one birefringent element (6) for the depolarisation of light in the end of the cavity adjacent the laser rod, the birefringent element preferably consisting of a pair of lens elements (7) and (8) spaced apart and at least one of which said elements is formed from birefringent crystalline material.
