The Difference Between Fiber Laser and CO2 Laser

-
Image
The main difference between the fiber laser  and the CO2 laser is that the working materials of the two are different. The working material of the fiber laser is optical fiber, and the working material of the CO2 laser is CO2, which belongs to the gas laser. In addition, the power of the two is relatively large. The difference is that fiber lasers are currently used from a few hundred watts to thousands of watts, while CO2 lasers typically   have a power range of 80W to 600W. The photoelectric conversion efficiency of fiber lasers is higher than that of CO2 lasers. Fiber lasers are superior to CO2 lasers in terms of cutting quality and speed. Fiber lasers are lower than CO2 lasers in terms of use and maintenance costs. Higher than CO2 lasers ; in addition, both fiber lasers and CO2 lasers require a chiller to cool and cool them.

Femtosecond lasers extend glass cleaving to mixed materials

Filamentation cutting is a relatively new process that uses ultrashort-pulse (USP) lasers to cut a wide range of glass substrates, from soft borosilicates to chemically hardened glass used in smartphone displays. Among the advantages of filamentation cutting are the ability to produce curved shapes and cut-outs, cutting speeds up to 2000 mm/s, and superior stress-free edge quality, which eliminates the need for post-processing. The high peak intensity created by a focused USP laser produces self-focusing of the beam because of the nonlinear optical Kerr effect, further increasing power density until, at a certain threshold, a low density plasma is created in the material. This plasma lowers the material refractive index in the center of the beam path and causes the beam to defocus. If the beam focusing optics are properly configured, this focusing/defocusing effect can be balanced to periodically repeat and form a stable filament, which extends over several millimeters in depth throu...

Why is the C band more suitable for 5G?

-
The C-band  has long been considered the preferred spectrum range for commercial 5G. According to some research reports, the recent 5G test research conducted by commercial organizations tends to be higher frequency band than C band, which involves 1GHz-100GHz illuminated, unlicensed band and spectrum sharing. "In the long run, the entire width of the 1GHz sub-band to 100GHz spectrum is the key to solving 5G application problems in various scenarios. However, in the short term, due to technical challenges, spectrum applications are not universal enough, 2019 to Millimeter waves will be used for 5G services or restricted in 2020," ABI senior analyst Prayerna Raina said in an interview. At present, mobile communication services use bands below 6 GHz, so the use of high frequency for mobile broadband is still a strange field for mobile operators. Similarly, 5G antennas and base station technologies such as MIMO are currently deployed in the 6 GHz subband range, which is gen...
