In the field of laser processing,such as drilling holes in thick glass,the 532nm green nanosecond laser is undoubtedly the”optimal solution”currently recognized by the industry.If the 1064nm infrared light is regarded as the”standard answer”in many conventional material processing,Therefore,532nm green light,with its unique wavelength characteristics and light-material interaction mechanism,becomes the ideal choice for dealing with glass-type brittleness and highly transparent materials.
The green light can be viewed as an upgraded version of infrared light-through the use of frequency multiplication technology,it not only inherits the stability and efficiency of infrared lasers but also reduces the wavelength by half,significantly enhancing the processing quality of high-reflective metals,semiconductors,brittle materials, and most polymers.This technology supports large-scale continuous operations and has become a”powerful tool”for addressing numerous challenges in material processing.There is no simple distinction between infrared and green light.It seems to be a”color competition,”but it is actually a precise match between technology and application needs.
As an important industrial material,glass is widely used in automotive,construction,medical,display and electronics,and the needs of different industries put forward diverse requirements for the thickness and machining accuracy of glass.
△ Demonstration of the Glass Drill
GR nanosecond laser with high photon energy,excellent material absorption characteristics and photochemical effect,can achieve efficient and precise machining of thick glass.The technology has the advantages of high pulse energy,short action time, small heat affected zone and so on,in the process of machining.With low loss and high precision,it significantly improves the quality of edge processing,and its control precision is improved by one order of magnitude.Compared with the infrared nanosecond laser,the green light process can make the upper and lower surfaces of the glass crack size strictly controlled within 100μm,far better than the infrared laser can usually achieve 250μm level,and significantly lower than the national standard safety limit of 300μm.By optimizing parameters such as laser power,pulse frequency,pulse width and scanning speed,it is possible to achieve a depth-to-diameter ratio of nearly10:1High-quality through-holes.
The green nanosecond laser technology can also effectively deal with the processing challenges brought by the high brittleness,high hardness,poor heat dissipation and large thermal expansion coefficient of glass materials,and the hole wall after processing is smooth,with little residue,significantly improving the reliability and overall quality of the finished product.In addition,this equipment is not only suitable for circular hole processing,but also can efficiently process complex geometric structures such as waist hole,non-standard hole,micro hole and text pattern.
Diamonds are favored in the industrial sector because of their hardness,but they are extremely difficult to cut and shape.As a non-contact process,laser cutting has the advantages of high efficiency,good molding and wide applicability compared to traditional methods,and has been widely used.
△Diamond (Diamond) Cutting Applications
Take the 532nm green nanosecond laser developed by Huahua Hongdu as an example,its wave length is short,the single photon energy is high,the single pulse energy can reach 2.5mJ,It can meet the strict requirements of diamond processing on quality and efficiency,and is easy to achieve ultra-high instantaneous power,with auxiliary blowing,can efficiently complete the cutting and reduce the heat effect.High beam quality(M²<1.2)allows the spot to be focused to the micron level,achieving high precision cutting,minimizing seam width and material loss,and preserving the value of the diamond .Only a small amount of black ablation layer is left on the cutting surface,which can be removed by simple grinding and polishing.The overall processing efficiency is significantly improved.
