“…It can be seen that the threshold pulse energy, at which the modification of the film surface begins, is 0.36 μJ for As 2 S 3 ( F = 136 mJ/cm 2 ) and 0.05 μJ for As 2 Se 3 ( F = 34 mJ/cm 2 ), respectively. It is worth noting that for As 2 S 3 the fluence exceeds the ablation threshold, which ranges from 7.2 mJ/cm 2 to 24 mJ/cm 2 for femtosecond 800 nm laser pulses according to Refs [ 41 , 42 ]. Presumably, modification of As 2 S 3 requires higher energies of laser pulses because the As–S chemical bonds are stronger than those of As–Se (260 and 230 kJ/mol, respectively) [ 43 ].…”

Chalcogenide vitreous semiconductors (ChVSs) find application in rewritable optical memory storage and optically switchable infrared photonic devices due to the possibility of fast and reversible phase transitions, as well as high refractive index and transmission in the near- and mid-infrared spectral range. Formed on such materials, laser-induced periodic surface structures (LIPSSs), open wide prospects for increasing information storage capacity and create polarization-sensitive optical elements of infrared photonics. In the present work, a possibility to produce LIPSSs under femtosecond laser irradiation (pulse duration 300 fs, wavelength 515 nm, repetition rate up to 2 kHz, pulse energy ranged 0.03 to 0.5 μJ) is demonstrated on a large (up to 5 × 5 mm2) area of arsenic sulfide (As2S3) and arsenic selenide (As2Se3) ChVS films. Scanning electron and atomic force microscopy revealed that LIPSSs with various periods (170–490 nm) and orientations can coexist within the same irradiated region as a hierarchical structure, resulting from the interference of various plasmon polariton modes generated under intense photoexcitation of nonequilibrium carriers within the film. The depth of the structures varied from 30 to 100 nm. The periods and orientations of the formed LIPSSs were numerically simulated using the Sipe–Drude approach. A good agreement of the calculations with the experimental data was achieved.

“…The loss is composed of the material loss and the confinement loss. According to previous studies, the transparent bandwidth of As2normalS3 glass can reach 0.6 μm at short wavelengths 20 and 12 μm at long wavelengths 21 . Thus, we set the material loss as 1 dB/m from 1 to 6 μm and then gradually increase it to 20,000 dB/m from 1 to 0.6 μm and 6 to 12 μm, respectively 21 , 22 …”

We designed an all-normal flat near-zero dispersion As 2 S 3 photonic crystal fiber (PCF) with orderly arranged air hole rings for generating an orbital angular momentum (OAM) supercontinuum (SC). We optimized the characters of chromatic dispersion and confinement loss compared with previous studies by carefully engineering the PCF. Simulation results show that, by launching a 100 fs 250 kW chirp-free hyperbolic secant pulse at 7 μm into a 5-mm designed PCF, a 9471-nm SC of OAM 1;1 forms from 757 to 10228 nm at a −40 dB level, which covers a 3.7-octave bandwidth. As the peak power increases, the higher-order OAM with a flatter chromatic dispersion profile in the normal dispersion region has a wider bandwidth. They are all highly coherent in the whole spectral range.

“…Among the available synthetic fiber, E-glass fibers are exploited in automobile applications due to their easy availability and its low cost compared to other synthetic fibers. [10][11][12] Herein, glass fiber reinforced polyester composites are mainly used in fabricating marine spare part systems and yachts. In recent days, mostly all recreational boats are fabricated using glass fiber reinforced polyester composite materials.…”

This research deals with the effect of stacking sequence over, the mechanical behavior of laminates that includes tensile, flexural, fractography, area of impact damage, and residual tensile strength. The angle‐ply laminate specimens were analyzed theoretically and correlated with experimental results. The highest interlaminar shear strength 32.89 MPa was exhibited by (60/30/60/30)S with better transverse stiffness of 444 N/mm. Among the developed laminates, (60/30/60/30)S showed the highest rate of residual strength degradation of 0.271. It has been found that an increase in interlaminar shear strength decreases the impact damage resistance of the composites. The angle‐ply laminate composites exhibited superior residual tensile and impact resistant properties when compared with uniply laminate composites.
