A beam quality measurement system for determining beam quality of a high power laser beam from a laser system by power-in-the-bucket (PIB) measurements in a laboratory environment. The system includes a beam compressor assembly for compressing the diameter of the laser beam, and a diagnostic bench assembly that receives the reduced diameter low power beam from the beam compressor assembly. The bench assembly includes a pinhole array positioned at a focal plane of a lens and that includes a plurality of different sized pinholes and a translation stage for moving the pinhole array. The bench assembly also includes a power meter that receives the focused beam after it has passed through a pinhole in the pinhole array, where the power meter generates a signal that causes the stage to move the pinhole array to position another pinhole when the power meter identifies a maximum power received from one pinhole.
