What is Crylink's 1064nm Nd YAG laser for material processing?

  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...

  Let’s learn about the 1060nm Nd:Glass laser for material processing The 1060nm Nd-doped phosphate glass laser has essential material processing applications and may be used for laser drilling and welding . Pump light is easily absorbed because Nd Glass has a long fluorescence lifespan, a strong energy storage property, a wide absorption spectral bandwidth, and a low heat conductivity of the glass foundation. Theory Laser Glass - Nd:Glass Nd doped glass has good optical performance, high energy conversion efficiency, is easy to process and low cost, and is suitable for Q-switching . It was used to make a 1060nm laser . The downside is that the thermal conductivity isn't as good as ruby's, and the temperature impact isn't as strong. As a result, adopting a complete water cooling system can still improve stability. Passive Q-switch - Cr:YAG Cr4+ YAG is a crystal that is utilized in lasers for passive Q-switching and is a novel laser crystal . It may be used in the wavel...
