  An introduction of the 1064nm Nd YAG laser for material processing When Nd:YAG crystals are used as the gain medium, the usual output wavelength in the infrared is 1064nm . Nd:YAG lasers are optically pumped lasers utilizing flash tubes or laser diodes. The 1064nm wavelength is easily absorbed by metal surfaces and has a high power density, allowing for a smaller kerf. Nd:YAG crystals are widely utilized in manufacturing because of their characteristics. Theory Gain medium - Nd YAG Neodymium ions in glasses operate as a laser gain medium, and Nd:YAG crystals may absorb wavelengths of 730nm—760nm and 790nm—820nm. When Nd is pumped into excitation, it generally emits 1064nm light following a certain atomic transition. In continuous mode, the greatest output power can be 1000W, and the highest average output power can be 400W; when the pulse width is 10ns, the energy can be 1GW/cm2 after being focused. Because of the smaller kerf of Nd:YAG crystals, lasers may have shorter output wav
