Development and application of ultrafast laser micro-nano manufacturing

Zhao quanzhong, vice President of nanjing advanced laser technology research institute, attended the summit and delivered the keynote speech of “progress and application of ultra-fast laser micro-nano manufacturing”. Ultrafast laser pointer have unique ultrashort pulse, at a relatively low pulse energy to obtain the high peak intensity, thus can solve many conventional methods to meet…

NASA terahertz oscillator development

NASA is developing a new type of probe that can observe the formation and structure of the universe, according to a report by McCombs consulting. The vast amount of radiation and mechanical interaction in the universe shapes the interstellar medium of galaxies and drives galaxy evolution (such as stellar winds and blast waves from jet…

It is reported that xi ‘an zhongke fine photon manufacturing technology co., ltd. has developed a series of ultra-fast laser pointer extreme manufacturing equipment, realizing the breakthrough of ultra-fine “cold processing” of air film holes in aero-engine turbine blades, filling the gap in China. Aircraft engine manufacturing level represents a country’s science and technology, industry…

New photoelectric laser pulses

According to foreign media reports, physicists from the national institute of standard technology (NIST) and the university of Colorado, by using ordinary electronic equipment, to create a photoelectric laser pointer that is 100 times faster than conventional ultra-fast laser pulses. The development could extend the benefits of ultrafast laser science to new applications such as…

Lasers are fired from space

Lasers make it possible to access the Internet quickly. Although communications can be made daily via undersea cables, they could be disrupted if the tunnel where the cables are laid is seriously disrupted. Transcelestial, a singapore-based entrepreneur, hopes to express the true potential of laser pointer communication, much like the Wright brothers’ invention of the…

Laser displacement sensor

987/5000 The laser displacement sensor is a measurement sensor using laser technology, which consists of laser pointer, laser detector and measuring circuit. As a new measuring device, the laser displacement sensor can accurately measure the position, displacement and other changes of the measured object, as well as the precise geometric measurement of displacement, thickness, vibration,…

Infrared LED and laser diode

Infrared light-emitting diodes (IR leds) and laser pointer diodes (LD) are not new technologies. They were invented in the 1960s. Recently, however, solid state lighting (SSL) has grown rapidly. LED and LD were originally developed for optical communication applications, but now they are widely used in data communication/telecommunications, consumer electronics, automotive and industrial fields to…

Femtosecond laser-induced shape memory polymers

Recently, the school of engineering sciences, university of science and technology of China (ustc) has made a new breakthrough in femtosecond laser pointer-induced material processing. The institute, in collaboration with the national university of Singapore, used femtosecond lasers to fabricate reconfigurable structures on the surface of shape memory polymers, discovered a new “polymer self-growth” effect,…
