The semiconductor end pumped laser marking machine adopts the international cutting-edge laser pumping technology to pump the semiconductor pump light (808nm) directly from the end face of the laser crystal and output the laser through the optical mirror group. The optical optical conversion efficiency of the laser is greatly improved, which can reach more than 45%. At the same time, the power consumption of the pump source is also reduced, which greatly reduces the power consumption of the chiller and the power consumption of the whole machine. End pump has better beam quality and higher peak power than side pump.
