LD-pumped solid-state laser

while the current average projection images show 60 in , power consumption should be 700 w ~ 800 w (200 w laser power is about mass production has been optimized in the case of realization of the power, because there is no mass production now, not yet reached this level). In the field of flat panel display, the current LCD TV, plasma TV market is very big, flat-panel TV applications, if the laser display technology, its power consumption can be reduced by 1 / 3 or 1 / 2. To 1 000 million flat-panel TV for four hours a day, a total of 29 billion kWh in electricity consumption, these households use more energy if laser TV will be saving 20 billion kWh per year in recent years in several large thermal power generation capacity the sum, equivalent to an annual reduction of 1.73 million tons of carbon dioxide emissions. The core parts of laser shows in the production process does not use any heavy metals, no waste water, waste gas, waste disposal, is a true display of environmentally friendly light source. The laser pointer  is used in the party.
Laser display technology not only can enter the existing laser film, laser projectors, laser rear-projection TVs, laser projection video wall displays and other products market, home theater, large-screen display system command, public information large screen, digital cinema , home theater, pilot simulation training, water screen imaging performance and other areas, but also to create a new display products, such as laser micro-projectors, laser projectors mobile phones, laser three-dimensional display. Laser invented soon, people began to study the laser show in 1996, previously used gas laser as the light source to achieve a full color scanning laser display, but life is short gas laser, inefficient, bulky and not practical in recent years , the semiconductor laser (LD) and LD-pumped solid-state laser (DPL) the rapid development of laser display technology opens the door to industrial development. Internationally Germany, Japan, the United States, Korea and other countries are putting in a lot of manpower and resources for all solid-state laser display technology research. International show giants have recognized that "a display area of revolution" to come. The laser pointer  can be widely used. The material of laser pointer should be carefully checked. The single beam of laser pointer is very bright. The international community such as Japan Sony, Mitsubishi Electric, Seiko Epson, South Korea's Samsung, Texas Instruments, United States, Germany Oushi Lang, Jena optics the technology giants are stepping up research and development. At present, the international laser display technology has been developed to the early stage of industrialization, and industrialization of key technologies supporting industry training and demonstration become the focus of development.
