​​END PUMP LASER MARKING MACHINE 8W-40W laser wave length 1064nm

End-pump laser marking machines (officially termed semiconductor end-pumped laser marking systems) utilize ​​end-pumping technology​​ to achieve high-precision industrial marking. The system employs ​​semiconductor laser diodes (LD)​​ as pump sources, emitting 808nm pump light via optical fiber coupling into ​​Nd:YVO₄ laser crystals​​. This excites Nd³⁺ ions in the crystals, generating 1064nm fundamental laser beams. These beams are amplified through resonant cavities (e.g., planar or folded cavities) to produce stable, high-quality outputs with ​​M² ≤ 1.3​​ and ​​peak power >60kW@10kHz​​. The device features a ​​compact all-air-cooled design​​ (no water cooling required), achieving ​​45%+ electro-optical conversion efficiency​​ and ​​10,000-hour operational lifespan​​, making it a cornerstone in precision manufacturing.
