3x3 Neodymium Doped Yttrium Aluminum Garnet NdYAG Crystal For Laser Marking

3*3 Neodymium-Doped Yttrium Aluminum Garnet NdYAG Crystal For Laser Marking

Introduction:

Nd:YAG lasers are used in manufacturing for engraving, etching, or marking a variety of metals and plastics, or for metal surface enhancement processes like laser peening. They are extensively used in manufacturing for cutting and welding steel, semiconductors and various alloys. For automotive applications (cutting and welding steel) the power levels are typically 1–5 kW. Super alloy drilling (for gas turbine parts) typically uses pulsed Nd:YAG lasers (millisecond pulses, not Q-switched). Nd:YAG lasers are also employed to make subsurface markings in transparent materials such as glass or acrylic glass and in white and transparent polycarbonate for identity documents.

Main Advantages:

• High gain
• Low threshold
• High efficiency
• Low loss at 1064nm
• High Optical quality
• Good thermal conductivity and shock characteristics
• Applicable to many laser working modes(continuous ,pulse ,Q-switch ,mode lock)
