The laser light source and low maintenance cost make the laser projector the mainstream of the market. Take the laser projector launched by BenQ at the Fuzhou Education Exhibition. The maintenance of light bulbs on mainstream brands is half a year, and the laser is three years. , Plus the initial cost of sales, is actually close to the cost of laser projectors.
In the past 3 years, in the field of laser projection, the number of manufacturers has doubled, the number of models in the market has increased tens of times, and the product types have fully and accurately covered all possible product lines. At present, the overall price of laser pointer projectors is too high, and they cannot be fully accepted by users. The cost price of laser light source technology will be reduced in the future, and laser projection opportunities in the market will be widely popularized.
Regarding the trend of laser projectors, industry insiders are very optimistic that the green laser pointer projection market will reach 300,000 units, an increase of 92% year-on-year. Using LIED technology to image one of the electrons in each molecule can avoid the critical problems of traditional electron diffraction. Traditional electron diffraction uses an “electron gun” to emit an electron beam onto a whole molecular sample. These electrons repel each other during flight, so the length of the pulse is increased, and it is difficult to set the shutter speed below 10 fs.
In the next stage of molecular “movie” production, other researchers hope that after transitioning from femtosecond red laser pointer pulses to attosecond laser pulses, an unprecedented slow-motion sequence can be generated. At that shutter speed, the atoms will move very slowly, and the movement of the electrons will become clear. This will be a crucial step, because the behavior of electrons will eventually control the movement of atoms in the molecule. “We have developed excellent techniques for observing ‘atomic actors’,” he said, “but to see real ‘movies’, we still need to observe the movement of electrons.”
Most of the researchers involved in the experiment also agreed that it was time to develop from the stage of research demonstration to the stage of technology application to study problems in various fields. If the researchers of these ultra-high-speed imaging equipment can convince chemists and materials scientists, this will really promote the vigorous development of chemistry and biochemistry.
