How much energy does different kind of glass absorbs when exposed to fiber laser?5 answersDifferent types of glass fibers exhibit varying energy absorption characteristics when exposed to fiber lasers. For instance, Er3+/Yb3+ co-doped silica fibers show absorption cross-sections at around 940 nm with weaker temperature dependence, making them favorable for achieving high-power laser outputs at 1.5 μm. On the other hand, Tm3+-doped tellurite glass fibers demonstrate significant average output power at 2.3 microns when pumped by a 794 nm laser diode, making them suitable for practical applications. Additionally, investigations on silica optical fibers exposed to gamma radiation show that the absorption behavior varies based on factors like radiation dose and wavelength, with a decrease in optical absorption observed with increasing light wavelength from 0.53 to 1.3 μm. These findings highlight the diverse energy absorption properties of different glass fibers under laser exposure.
How does the absorption of energy by different materials vary when exposed to laser radiation?5 answersThe absorption of energy by various materials when exposed to laser radiation varies significantly based on the material properties and conditions. Studies have shown that the absorption of laser energy on nanowire array targets can reach up to approximately 71% of the incident energy, surpassing solid flat targets' absorption levels under similar irradiation conditions. Additionally, the absorption of optical materials can increase due to exposure to ionizing radiation, impacting the analysis of laser-induced breakdown spectroscopy data retrieved from high-radiation environments. Laser radiation on solid bodies can lead to explosive melting and plasma formation, affecting the temperature field and material dispersion. Furthermore, research on powder materials like copper and nickel has explored the absorption of laser radiation and its correlation with the material's temperature under varying incident laser power levels.
•The higher absorbed energy, the higher damages in the composite materials ?5 answersThe absorbed energy in composite materials during impact events does not always directly correlate with the extent of damages. While higher absorbed energy typically indicates better impact resistance, it does not necessarily mean more damages. The energy absorption in composites is influenced by various factors such as material composition, stacking sequences, and manufacturing defects. Damage mechanisms like delamination, fiber breakage, and matrix cracking are observed during impact tests, but the relationship between absorbed energy and damages is not always linear. Detecting damages in composite materials, such as interlayer damages, requires specialized techniques like ultrasonic methods. Therefore, while higher absorbed energy can enhance impact resistance, the level of damages incurred is influenced by multiple factors beyond just the absorbed energy level.
What is the relationship between mass ratios and the failure of fibers to spread and absorb impact energy?4 answersThe relationship between mass ratios and the failure of fibers to spread and absorb impact energy is influenced by various factors. One factor is the properties of the matrix material and the alignment level of the fibers. Another factor is the geometric conditions and energy equilibrium of the material. Additionally, the inter-fiber spacing and the redistribution of stress around fiber breaks through the viscoelastic matrix can also influence the failure mode and energy absorption. The failure behavior of composites with different matrices and fiber-matrix interfacial bonding can vary, with some composites failing in a brush-like manner and others failing by propagation of a single crack. The nucleation process of critical flaws that induce brittle failure is also time-dependent. Overall, the relationship between mass ratios and fiber failure in absorbing impact energy is complex and influenced by multiple factors.
What are the potential applications of using fibers to enhance energy absorption in impact-resistant materials?4 answersFiber reinforcement has shown potential for enhancing energy absorption in impact-resistant materials. Basalt fiber was found to significantly increase the impact resistance of ultra-high performance concrete (UHPC) slabs.
