Multiple analysis - The core advantages of MOPA lasers(3)

Another important index affecting the laser processing effect is the target surface power density, “peak power density = peak power ÷ spot area”, in which spot area is related to the laser beam quality, collimating spot diameter and the configuration of the field lens. Domestic nanosecond pulse lasers in the power range above 100W are generally about 1.6~1.8 beam quality. The high brightness GMZ series of lasers provided by Guangzhi Technology, M2 can be controlled within 1.5, if customers have requirements, 200W~300W high-power models can also achieve 1.3, effectively ensuring the quality of processing. In the accurate and fine processing of ultrafast laser, besides the beam quality factor, the factors such as dispersion and aberration also have a great influence on the morphology of the focal spot on the material. To control these parameters requires careful works in the laser design, especially in the design and testing of the space optical lens.

Laser spectrum is a key parameter affecting the absorptivity of materials. The general fiber lasers are mainly concentrated in the bands of 1060nm, 1550nm and 2000nm, which are respectively mainly suitable for the processing and application of metals, silicon wafers and polymer materials. In a large number of copper and photovoltaic silicon wafer processing used in industry, green laser has a special advantage because of its high cold absorption rate. Ultraviolet lasers also have special advantages for thick PCB or fine glass cutting applications due to their high photon energy.

In addition to optical parameters, the durability, flexibility and easiness of using the electronic control system directly determine the user's experience of the product. Among all the industrial lasers, the MOPA nanosecond pulse laser has the most complicated electronic control system. Because the MOPA laser has a wide range of pulse width and repetition frequency It requires high-speed switching, which involves internal parameters switching from oscillator to multistage amplifier. While control card signals in the market are diverse, if they would not well adapted, it is easy to cause damage to the laser. For the ultrafast laser, it is very important that the main part of the laser works stably, and the refrequency and amplitude of the output light are controlled mainly by the acousto-optic devices at the end. Because MOPA laser uses electrically modulated LD as the seed source, it is more flexible, which can shape the pulse shape, and also can flexibly control the height of the first pulse and realize the output of pulse series.
