Recently, Purdue University in West Lafayette, Indiana, announced a new laser processing technology - roll-to-roll laser induced superplasticity.
According to reports, this technology can print metal like a newspaper, and make metal components with higher smoothness and higher flexibility, which can achieve very high printing speed and precision. The metal components are used in high-speed electronic equipment to reduce excess thermal resistance and reduce the heating of electronic equipment.
The green laser pointer induces superplasticity. The CO2 laser is used to induce the "superelastic" behavior of different metals in a short time by high-energy laser shock, and the metal flows to the nanometer-scale rolling stamping device to break through the metal forming limit. This method solves the problem of rough surface roughness of metal circuits and low resolution of conventional molds, and can form a smooth metal circuit in the accuracy of nanometer order. The metal circuit made by this method has a smooth surface and no excess metal adhesion, which can greatly reduce the thermal resistance of the semiconductor during operation, and provides another solution for solving the heating problem of the electronic device.
In addition, the green laser pointer technology can also create nano-structured touch screens that interact with light and generate 3D images while creating cost-effective and sensitive biosensors.
It is reported that the Vbeam Prima 595nm pulsed dye laser (PDL) produced by the cosmetic laser manufacturer Candela has been approved by the US FDA.
By adding a wavelength of 1064 nm and other new features, the laser will be able to effectively treat a variety of skin diseases including rosacea, wine stains, acne, facial veins, lower extremity vasodilation and spider veins, scars, benign pigmentation Lesions, wrinkles, skin blemishes, stretch marks and photoaging phenomena.
Eric Bernstein, MD, director of laser surgery and cosmetic dermatology at the Laser Surgery Center, said: "In clinical studies using Vbeam Prima lasers, symptoms were significantly reduced after four treatments for patients with facial redness and rosacea."
In addition, the green laser pointer has a 50% increase in power, a 15mm spot size, contact and spray cooling, and a daily calibration for a significant increase in dye life.
