Semiconductor end-pumped laser marking machine is called end-pumped laser marking machine. Laser diode is pumped by laser diode (LD), and the laser is injected from the end face after being coupled by optical fiber. So that the pump beam into the gain medium and cavity mode space to the greatest degree of overlap, which can be high-power and high beam quality laser output. Its integrated structure, no optical pollution, power coupling loss and air cooling, with other lasers do not have the high efficiency, long life and less maintenance and other properties.

LD in the state of continuous work up to tens of thousands of hours of life in the pulse of the working state of up to 10 times the number of pulses, compared to the flash in the pulse and continuous working life of only 10 times and 2000 hours.
Stability: LD pumped solid-state lasers can usually be kept at less than one percent. Flash output power there is a lot of noise and instability, which also led to the instability of the output power.
(M <1.2), the output laser stability is high, the marking effect is easier to debug, the marking line is thin, more suitable for some of the more detailed graphic markings. Machine performance and stability, air-cooled to avoid the water tank, small size, low power consumption.
