The stronger the laser energy, the stronger the irritation of the skin, the greater the degree of damage, the better the effect.

As the Asians are more sensitive to light, laser exposure to high energy is also high risk, reasonable to set the laser energy size, the density of irradiation points is very important.

After erbium laser irradiation treatment, because of the healing mechanism of human skin trauma, these target tissues as a repair center, epidermal new healing, dermal fiber thickening, skin comprehensive improvement.

The current 1550 nm erbium 1000mw laser pointer for rejuvenation (facial skin rough, thick pores, aging wrinkles), repair acne dents, repair scars (surgical scars, caesarean section scar, burn scar), stretch marks repair A very good effect.

In addition, erbium laser can also be used for chloasma and seborrheic alopecia treatment.The wavelength of the thulium laser is at the peak of the water absorption energy, and the closer the laser wavelength is from the peak of the energy absorption, the faster the energy absorption is.

The more shallow the penetration is (0.2 mm), the irradiated tissue is rapidly vaporized and the thermal damage is minimal The As the heat damage of thulium laser tissue is small, the scab (shallow tissue block formed by living tissue shedding) is shallow, and the recovery time after operation is shortened, and it is easy to obtain pathological analysis.

NASA is working on a long-term technical demonstration of laser communications that could eventually generate high-speed Internet between terrestrial satellite reception stations and space trajectories or spacecraft on other planets.

The connection speed of the network will be far more than the speed of the existing radio frequency.

This beam will connect the spacecraft and the antenna on the earth.

Faster speed means that scientists can get test results faster from spacecraft and improve communication between humans and astronauts on the ground.

It is vital to conquer the distant stars of mankind.Researchers are now using the filaments produced by the picosecond lasers to create a path again through the fog in the lab, which may allow other types of laser beams to pass through the fog and clouds unhindered.

When the filaments produced by the ultrafast laser pulses pass through the fog, their attenuation is not as much as expected, because when the filament itself is blocked, it absorbs energy from the surrounding photon bath and replenishes the energy in the filament.Femtosecond lasers produce three to four filaments, which carry about 15% of the total beam energy.

Internationally renowned third-party inspection and testing organization DEKRA Dekai Group will be the world's largest innovative laser coating stripping (LCR) robot for LR Systems BV testing.

Developed by LR Systems, robots will use a 20kW high power laser pointer to remove coatings from commercial and military aircraft of any size with the greatest accuracy.

In addition, the robot removal process is faster and cleaner than today's methods, and can significantly reduce the aircraft stall time in the ground.

"I am delighted that DEKRA will support our global LCR team," said Paul van IJsselstein, CEO of LR Systems BV.

"I believe our first system development and rollout will benefit from DEKRA's unique Professional knowledge and experience, DEKRA Group's professional support can further add value to our global robotics solutions in the maintenance industry.

"DEKRA Group will be involved in the entire testing and certification process, from safety performance evaluation, component testing, and factory acceptance testing to the installation of the first LCR robot.

Universal fiber polarizer has a short board, Xi'an Institute of Optics and Fine Mechanics, Chinese Academy of Sciences Institute research team femtosecond pulse laser-induced change in refractive index silica fiber cladding, the invention of the femtosecond green laser pointer lithography fiber polarizer a new structure has been recently won the national invention patents.Fiber polarizer is widely used in fiber lasers, fiber optic sensors and measurement field, the traditional fiber polarizer are the following: a polarizer type fiber polarizer, D-type fiber polarizer, polarizers and other fused taper.

Among them, the spatial structure of the polarization mirror optics fiber polarizer involved more, not easy to adjust.

D-type fiber polarizer due to the precision grinding and fiber coating is very high, so that the finished lower efficiency.

Fused fiber polarizer is an optical fiber at a high temperature molten state and then pull the cone shaped crystal to generate polarization anisotropy generated effects, the bandwidth is generally about 30nm.Xi'an Institute of Optics and Fine Mechanics Institute Transient Room Cheng Guanghua, Zhao Wei, Quartz for technical problems of conventional fiber polarizer present in-depth research, the invention of the femtosecond laser lithography fiber polarizer a new structure: the use of flying second pulse laser induced silica fiber cladding refractive index changes in the fiber core having generated around the same polarization characteristics of the light guide nanometer periodic grating.

In the fiber core evanescent wave transmitted light is modulated by the surrounding nano stripes, horizontal and vertical polarization components of different scattering properties perpendicular to the plane of vibration nano-scattering component is very obvious that this is a large number of scattered polarization state, parallel to the plane of Nano the polarization state of low loss, after a certain length of the transmission, and ultimately achieve higher extinction ratio (> 20db).

Since the polarization insensitive wavelength scattering characteristics and the relationship between the nano-grating, nano-stripes for different wavelengths have high polarization extinction ratio.
