1. using the independent research and development Q-switched lasers with international leading level, excellent beam quality, pulsed duration less than 3ns, very small thermal effect

2.high-power beam expander and dual-band aberration focusing mirror is used in conjunction with the perfect design to a small focused spot to 5um

3.using high precision X-Y-Z CNC electronic displacement platform, repeat positioning accuracy up to 1um

4.the use of laser and CCD microscopy confocal aiming optical system to display the micron engraved diamond image and laser engraved lines clearly at the same time, and the operator eyes don't fatigue

5.specially designed software to input and edit any text and graphics, easy to operate

6.operation lifetime>20000 hours, total power consumption < 200W, air-cooled, no need to maintenance

7. non anydamage to the diamond, marking precisely and  beautifully
