The professor led the “Crystal Color” scientific research team and invented an original scientific idea and technical solution. Using a mid-infrared broadband femtosecond pulsed laser to pump a monolithic chirped structure of lithium niobate nonlinear superlattice photonic crystal — white light laser pointer crystal, can produce high-performance white light laser. White laser crystal materials have the characteristics…

Greatly improve the development level of green laser pointer technology
In today’s era, various developed countries have placed non-linear optical crystals, laser pointer devices and applications on a priority development position, and have been listed as important strategic measures in their respective high-tech development plans, with great attention and support. From the perspective of the technological level of the entire field of nonlinear optical crystals, devices and…
Advantages and application prospects of white light laser
Compared with ordinary white light sources (such as sunlight, incandescent lamps, white LED lights, etc.), white laser light sources, short-wave laser light sources and super continuous laser pointer light sources have the advantages of high brightness, strong peak power and wide frequency coverage. Scientific research, national defense and military, lighting, communication technology, information technology, industrial production, biomedicine,…
Coherent white light in infrared band green laser pointer
Since Mayman invented the first laser pointer (ruby laser) in 1960, laser technology has achieved tremendous development and great achievements in the past 50 years, and has played an important role in many fields of human society. . The development of laser technology is changing rapidly, from the early gas laser (He-Ne laser), high power carbon dioxide…
Laser pointer performance far exceeds traditional sunlight
The existing laser technology has always had a shortcoming, that is, it can only emit light of a single wavelength or a narrow band. How to expand the frequency of the laser to form an ultra-wideband, super-continuum, coherent white light laser covering the ultraviolet, visible and infrared bands is still a dream that has not…
So important for unmanned lidar
The auto industry is always tinkering with some new words to torment us. Thanks to it, we now know that driverless cars are “coming soon.” Some manufacturers predict that autonomous vehicles will enter the commercial market, the earliest time is 2021. However, when the new technology arrived, the price was high, and most ordinary people…
Technology can solve this laser pointer problem
There is a technology that can solve this laser pointer problem, that is, solid-state systems, but solid-state systems are much cheaper than traditional lidar systems. Claims that it has manufactured $ 250 components for use in so-called S3 cars. It’s a pity that the system’s fidelity is low. It’s only useful when the car is driving at…
Can lasers be used to accelerate electrons instead of synchrotrons?
Particle acceleration no longer requires accelerators of several kilometers in size. By using laser technology, particle acceleration can be performed within a few centimeters. The new laser pointer tail wave field (LWFA) technology uses a single laser pulse to accelerate the electron beam to the energy level achieved by large equipment. The team led by Simon Hooker…
What Is The Difference Between Laser Microprojection And Traditional Laser Theater?
The strategic positioning and product support are different: the laser pointer theater is positioned at the high end, pursuing a large-screen experience and theater effect. From the perspective of user experience, traditional brands are equipped with Fresnel optical screens. The Fresnel optical screen can effectively resist the ambient light, which can be said to be the soul…
What Is The Difference Between Laser Cinema And Laser Microprojection?
Thanks to the improvement of people’s consumption level, the market demand for home theaters continues to rise, and the laser theater concept has become very popular nowadays. Traditional home appliance brands such as Changhong and Hisense have been deployed early, and Internet brands have also actively entered the market. The much-anticipated M brand laser pointer laser projection…
