Respectively, 6000W-BB-200x200 and L2000W-BB-120 water-cooled laser power/energy sensors have 200 x 200 mm and 120 mm apertures and measurement capabilities of 100–6,000 W and up to 2,000 W. With 120 mm aperture, L100(500)A-PF-120 laser power/energy sensor measures lasers for ~1 sec exposures at up to 6,000 W or continuously up to 100 W (500 W with heat sink). Scatter Shields 30K-W and 10K-W reduce heating effect of backscatter on surrounding sensor surfaces when measuring 30 and 10 kW lasers.
