No vibration caused by flowing water so that the laser beam quality and pointing performance are more stable.Electric-to-optical conversion efficiency is high and the operation time of the lamp is elongated.The sealing is very good and there is no water leakage for long time use.The laser has first-pulse compression function and the laser pulse peak power is more consistent. Thus the marking quality is much better since the marked lines are also uniform.Technical Specifications Model ATM-DPSS-50 ATM-DPSS-75 ATM-DPSS-100 Pump mode Laser diode-pumpedLaser wavelength 1064nmLaser power* 50W75W100WLaser beam diameter 3mm3mm4mmLaser power stability ±3%Pulse repetition rate 1 50kHzScanning speed ≤7000mm/sMarking depth ≤0.35mm≤0.45mm≤0.55mmMarking resolution 0.02mmMinimum marking character 0.50mmStandard marking field 110mm×110mm(others available upon request)Cooling method Closed water coolingMarking software Based on WIN XP/2000Environment requirement Temperature 5°C-35°C, humility: 0-95%Electric requirement 220VAC, 4KVA220VAC, 5KVA220VAC, 6KVA
