 Laser Surface Amorphization Alerter l'administrateur Recommander à un ami Lien de l'article 

In this study, a cadmium sulfide (CdS) line with a diameter of 204 nm and a length of 15 μm was used as the core design of the optical cavity (Fig. 1). The high refractive index of the nanowires causes the incident light to have a high reflectivity factor at the end face and be guided by the nanowires. This arrangement forms the Fabry-Burrow cavity, which, when activated by an external light source, forms a laser. The laser wavelength thus formed depends on the refractive index around it. By measuring the wavelength of the most powerful laser output, the refractive index of the liquid immersed in the nanowires can be determined.

There are a variety of methods for surface nanocrystallization of materials. There are a large number of surface nanocrystallization technologies. It is a surface layer which can realize the nano-characteristics by means of laser surface treatment technology and nanometer technology. It can be collectively referred to as laser surface nanocrystallization technology; More generally referred to as laser nano-surface engineering technology, is directly or mainly the use of laser this specific technical means to directly change or add material to change the surface of the solid material is treated, the composition or structure, so that the formation of nano-crystal Grain or a certain nanoparticle composition of the surface layer. Or the use of laser etching, laser embossing, laser hair, laser micro-nano modeling and other means to achieve nano-structure on the surface of the material.

 The Latest Development of High Power Single - mode Fiber Alerter l'administrateur Recommander à un ami Lien de l'article 

If there is a clear trend in the field of laser technology, that is the rise of fiber lasers. In high power cutting and welding applications, fiber lasers have been from the high-power CO2 lasers and solid-state lasers to seize a large number of market share. At present, some mainstream fiber laser pointer manufacturers are exploring many new applications to meet more market demand. In high-power fiber lasers, single-mode systems have satisfactory characteristics: they have high brightness, can focus to a few microns to the highest strength. They also have the largest depth of focus, which makes them ideal for remote machining.

What are the challenges of this single-mode high-power fiber laser? These challenges can be divided into three main areas: improved pumping, designing active fibers with low optical losses and operating only in single-mode operation, and correct measurement of the resulting radiation. In the active fiber design for high power single mode operation, there are two general parameters to optimize: doping and geometry. All parameters must be determined to achieve minimum loss, single mode operation, and final high power amplification. The perfect fiber amplifier will provide over 90% of the high conversion rate, perfect beam quality, and output power limited only by the available pump power.

However, lifting a single mode system to a higher power may result in a higher power density within the active core, an increased thermal load, and many non-linear optical effects such as stimulated Raman scattering (SRS) and stimulated Brillouin scattering (SBS). The most striking is the typical effect of the ytterbium-doped quartz fiber, and it is well known in the early days when fiber lasers are not as pure as today, and this is phototaxis. In this process, due to the interaction of the green laser pointer material, a defect center or a color center is formed in the material. This effect is parasitic: it converts pump photons into heat, which results in lower magnification and increased heat load.

Yb (Yb) fiber is a typical main medium for high power single mode fiber lasers. But over a certain threshold, they will show a new effect, the so-called transverse mode instability (TMI). At a particular power level, a high-order mode or even a cladding pattern occurs, where energy is dynamically transferred between these modes and the beam quality is reduced. The beam starts to fluctuate at the output. Since the discovery of TMI, TMI has been observed in various fiber designs from step index fiber to photonic crystal fiber. Only its threshold varies with geometry and doping, but it is roughly estimated that this effect occurs after the output power exceeds 1 kW. At the same time, this effect is combined with the thermal effect inside the fiber, and has a strong correlation with the photo-induced darkening effect. In addition, the sensitivity of fiber blue laser pointer to TMI seems to be affected by the core modal composition.

Step Geometry The geometry of the fiber produces a number of parameters for optimization. The diameter of the core, the size of the pump cladding, and the difference in refractive index between the core and the pump cladding can be adjusted. This tuning depends on the doping concentration, that is, the concentration of Yb ions can be used to control the absorption length of the pumped radiation in the active fiber. Other dopants may be added to reduce the thermal effect and to control the refractive index step.

But there are some opposite requirements. In order to reduce the nonlinear effect, the fiber should be shorter. However, in order to reduce the heat load, the fiber should be longer. The photodegradation increases with the square of the dopant concentration, so it will be better to have a longer doped fiber. The initial advice on these parameters can be found in the simulation. Some parameters, such as thermal behavior, can be simulated but are difficult to predict, especially since the photo-darkening is low and can not be measured by accelerated testing. Therefore, direct measurement of the thermal behavior in the fiber will contribute to the experimental planning.

Another important parameter in fiber red laser pointer design is the cut-off wavelength, which is the longest wavelength that allows more modes in the active core. High-order mode greater than this wavelength is not supported. In addition to the nature of the fiber itself, there are several ways to influence the amplification process and loss mechanisms, such as fiber bending or seed beam time characteristics and spectral characteristics.
