The difference between picosecond laser cutting machine and nanosecond laser cutting machine

In recent years, with the continuous improvement of technical requirements in industrial production, the regulations on special tools for production and processing have continued to be higher and higher. The development prospects of special tools for micro-fine fiber laser cutting are also approaching market demand and The development trend of the extremely fast laser industry has slowly created a market demand for the development and design of picosecond laser fiber laser cutting and full femtosecond laser automatic cutting machines with nanosecond fiber laser cutting as the core.

The production and processing method of laser is to use high-efficiency energy laser light to directly irradiate the surface of the raw material after focusing to cause physical or chemical changes to produce laser cutting. It is essentially a heat treatment method, but because the effect time is short, generally In the range of many nanoseconds, the area of u200bu200bthermal hazard is small, which can ensure the actual effect of production and processing and the production and processing rate.

In today’s popular sales market, the most common special tool for laser cutting processing is a nanosecond laser. With the technical regulations of industrial production not only improved, the thermal hazards in the field of nanosecond lasers The utility has been enlarged, and the actual effect of poor derivation caused by the thermoelectric effect is not accepted by the sales market. A new special tool for laser cutting processing has emerged from time to time, which meets the needs of the market and is also a technological improvement in the laser field. In the field, it is called micro-fine ultra-fast laser cutting processing system software, generally called picosecond laser fiber laser cutting or full femtosecond laser automatic cutting machine.

The picosecond laser fiber laser cutting has a slightly shorter single pulse time, and the single pulse effect time is only a few picosecond laser time, so its thermal hazard is very small, or even negligible. Compared with the production and processing of nanosecond fiber laser cutting, there is no refining of raw materials in the entire production process, and the production process is clean. The digestion and absorption of laser kinetic energy is less dependent on raw materials or light wavelengths. Therefore, in the micro-fine laser cutting processing industry, the picosecond laser fiber laser cutting and the full femtosecond laser automatic cutting machine of the extremely fast laser cutting processing system software show a wide and full indoor space, and its production and processing characteristics are ultimately the key to its future. Influence.

Compared with nanosecond lasers, picosecond laser fiber laser cutting has higher quality in actual production and processing efficiency and production and processing speed. In the sales market, picoseconds also have a wider indoor space, such as Solar panel laser ion implantation (narrower pattern boundaries), OLED fiber laser cutting (less edge collapse), ductile raw material laser drilling machine (faster speed), these can guarantee the things that cannot be done in the nanosecond time period. The key depends on the hazard of the thermal hazard zone. From the figure below, we can visually see the difference between extremely fast picosecond and nanosecond lasers. On the picture, everyone found that the thermal hazard area and the hazard caused by the thermal hazard to the raw material in the nanosecond range, and the extremely fast picosecond laser fiber laser cutting is basically a negligible thermal hazard, so the actual effect of production and processing is more ideal. In addition, the efficacy time is shorter, the precision is higher, and the production and processing speed is also fast.

It is precisely because of the low-fire, cold-dissolving, and high-precision characteristics of extremely fast picosecond laser fiber laser cutting. It is used in stainless steel, aluminum, aluminum alloy, blue gemstone, porcelain, laminated glass and other raw materials It has extraordinary main performance and is widely used in scientific research, microbiological equipment, photovoltaic power generation, electronic equipment manufacturing, semiconductor equipment and other industries with the same influence as a sure new darling.

Naturally, the popular laser cutting processing sales market in the current sales market is still dominated by nanosecond lasers. The reason depends on the high cost of picosecond ultrafast fiber laser cutting, and the future development trend is inevitable. It is towards the development trend of picosecond laser and femtosecond laser industry, the future can be expected
