The current development trend of end pumped lasers is towards ultraviolet lasers and narrow pulse widths. Relatively speaking, the focused spot diameter of the ultraviolet pump laser is smaller, resulting in more precise marking effects; Compared to infrared pumps, metals have a higher absorption rate of ultraviolet light and are more suitable for marking on metal and glass materials. Narrow pulse width lasers have a shorter interaction time with processing materials, lower thermal effects, and more aesthetically pleasing marking effects.
UV laser marking machineadopted355nm ultraviolet light has a very small focused spot and a minimal heat affected zone during processing, making it mainly used for ultra-fine marking, special material marking, and engraving. Has the following characteristics:
1Adopting high-precision technology355nm end pumped ultraviolet laser;
2Laser beam fundamental mode, short pulse width, high peak power, high repetition rate;
3Wind cold water circulation cooling, with efficient cooling function of water cooling and compact volume of air cooling;
4Excellent overall performance, good stability, high conversion rate, and low energy consumption.
5High photoelectric conversion efficiency and long service life. Low power consumption, suitable for marking various non-metallic and metallic materials, especially suitable for applications with high precision and precision requirements.

narrow pulse width |
1atAt 10KHz, the pulse width of LSU3EI can reach 15ns. Generally, the pulse width of UV lasers on the market is around 20ns. 2If the pulse width is narrow, the interaction time between the laser and the marking material is short, the thermal impact is small, and it is conducive to generating high peak power. |
|
High peak power |
1Peak power is superior to other brands of UV lasers on the market; 2At the same average power and pulse repetition frequency, the narrower the pulse width, the higher the peak power. The higher the peak power, the wider the range of suitable marking materials, which can be used to mark certain harder materials. |
|
high repetition frequency |
1Due to the narrow pulse width achieved at higher repetition rates, ultraviolet lasers can support rapid marking. 2Fast marking speed is one of the important indicators that many customers pursue. |
|
High pulse stability |
The consistency of laser pulses is good, with the energy of the previous pulse and the energy of the next pulse being the same, resulting in the same marking effect. After amplification, there are fewer explosive points and weak points observed, which is one of the important indicators pursued by many precision marking customers. |
