A British company recently said it is developing a new type of geophysical weapons, that is, the use of laser temporary adjustment of the atmospheric environment, can improve the visual sensitivity of enemy targets, or to prevent high-energy 1mw laser pointer weapons attacks. The new geophysical weapon works by using lasers to change the ionosphere in the Earth's atmosphere, helping to monitor the sensor for better detection of targets or destroying laser weapons aimed at reconnaissance platforms.
This concept uses the Kerr effect, that is, when an electric field is applied to a substance, its refractive index will change. When the high-speed pulsed laser through the atmosphere will produce electricity, can make the ionosphere change to similar lens structure. This lens has two aspects of the role, on the one hand through the refraction to change the propagation path of electromagnetic waves, so that the incident wave is introduced into different directions, so that high-altitude reconnaissance sensors get more condenser, improve the visual sensitivity of the enemy target; On the other hand, you can use the 5mw green laser to create a "plasma", through the reflection and diffraction damage to the propagation of laser beam, to prevent the enemy high-energy laser weapons attack. In addition, this process is reversible, once the stop firing laser pulse, the atmosphere will return to normal state, will not cause harm to the environment.
As the manufacturing industry continues to evolve to the whole process of global trends, lasers are changing the value proposition of some traditional processing methods, such as paper cutting and stamping of materials in the packaging industry. Amazon and some other companies are driving a change from "traditional fixed-size carton packaging" to flexible packaging. The so-called flexible packaging, that is, the use of new plastic materials, and site to create, can fully meet the needs of specific goods.
This new type of flexible packaging is lighter and safe to biodegrade, both to reduce the cost of transportation and packaging, but also reduce the environmental pollution, which is an important future performance indicators of the Amazon. This change can be achieved because the 50mw green laser is different from the tool, they are not blunt, and can provide far more than the mechanical system repeatability and accuracy.
The new multilayer plastic has a strong absorption peak at a particular spectral line within the CO2 spectrum, or the wavelength of the laser can be changed as the plastic layer moves in layers during the cutting process. Instead of a large cutting system, a laser array is required to achieve ablation, with little heat generation, and hundreds of feet per second to cut a large format. The lasers that meet this particular application require high accuracy on a single spectral line with a peak power and average power ratio greater than 100: 1 or higher and a very high pulse frequency (> 10 kHz).
Traditionally, such high peak power and repetition frequencies require Q-switches or other external modulation techniques, which are too expensive for large-scale deployments requiring cost-effective packaging. In contrast, the CO2 100mw laser pointer we are developing are small in size and require no external modulation to achieve peak power on kilowatts and meet the needs of the packaging industry. In fact, the latest trends in the field of manufacturing, medical and materials science are driving the CO2 laser from the value proposition of "power-based price" over the past half century, evolving into "customer-centric, tailor-made" era.
The cutting laser has the most compact structure on the market today and is easy to integrate into the cutting system. Airtight cabinets with built-in drying system for use in harsh production environments, especially for 2D / 3D slab cutting and copper, brass and aluminum cutting. CUT series of new diode pump module, higher power, more cost-effective; new fiber module design, red laser pointer damage threshold increased by 3 times, more reliable performance; digital power module efficiency> 40%, customer operating costs lower; Redundant protection; built-in reliable safety switch <100 ms. At present the CUT series has reached the maximum power of 12 kW, with high cost.
