Product Details
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)
