  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...

 Benefits of the Scanning Mirror CRYLINK provides various types of high-power X/Y scanning mirrors , mainly including silicon scanning mirrors and quartz scanning mirrors, for laser scanning mirror systems above 6Kw. Laser wavelengths include 355nm, 532nm, 1064nm, and 10.6μm. Description Thanks to the special coating technology, it is possible to ensure that the mirror dissipates heat quickly and with little temperature rise at the laser focus during use. The amount of change in the shape of the used surface is very small. The mirror has a high threshold of laser damage, which can meet the requirements of long-term stable use of the scanning mirror. High-Quality Substrate · High-quality substrate material, rough machining, and polishing quality are the main factors affecting the performance of optical elements. · The mirrors are made of imported Corning 7979 and 7980 materials with guaranteed quality; · For high-power laser optical elements, it is particularly required ...

  By applying electric field control to the electro-optic crystal, the refractive index of the electro-optic crystal in a certain direction can be changed, so that the Pockel unit of the electro-optic modulator can be used as a variable half wave plate to change the polarization state. The wave Kerr unit of the electro-optic modulator is placed between two vertical polarizers to realize light intensity modulation. Electro optic effect can be divided into transverse electro-optic effect and longitudinal electro-optic effect. In the transverse electro-optic effect, the propagation direction of light is perpendicular to the electric field, while in the longitudinal electro-optic effect, the propagation direction of light is parallel to the electric field. Crylink's Pockels battery uses a protective window with high-quality AR coating to ensure high transmission rate and prolong the service life of the equipment. The half wave voltage of longitudinal electro-optic effect is independ...
