Output power as power in the bucket (aperture diameter 30 mm) after a water column of 10.1 cm with different laser spot sizes and input powers. For large spot sizes and low input powers, the power in the bucket is constant with time while it varies strongly for small spot sizes and high input powers. The latter arise from thermal lensing and thermal blooming.
