At present there are two kinds of main laser sub-surface engraving machines. One is a diode pumped Nd: YAG laser sub-surface engraving machine, the other is a lamp pumped solid state laser sub-surface engraving machine. Diode pumped laser sub-surface engraving machine uses a diode pumped solid state such as Nd: YAG to generate laser, it has high laser output speed, and no consumables, but the machine price is very high. Lamp pumped Nd: YAG Laser sub-surface engraving machine adopts Xenon lamp pumped Nd:YAG to generate the laser. Generally the engraving speed is limited by the repetition rate, and it needs to change Xenon lamp every two or three months, but the price is cheap. Lamp pumped Nd: YAG laser sub-surface engraving machine can meet the common requirement, and it has less risk with high rate of return. LGYAG-800/900 series laser sub-surface engraving machine uses Xenon lamp pumped Nd:YAG laser technology.
