“…All of the aforementioned laser generations were generated through a solidstate laser setup while no research has yet to be reported based on a carbon nitride SA compatible with an all-fiber laser configuration. Excellent optical properties have also been reported on amorphous carbon nitride (a-CNx) including changeable bandgap, and high transparency and photoconductivity [13,14], but no related research works have yet been done in the field of photonics. With the few works reported on g-CN, all of which was based on solid-state laser, none was ever reported on a Q-switched operation in 1.5 μm region.…”

This research presents the first-ever demonstration of a passively Q-switched fiber laser in the 1.5 μm wavelength region using amorphous carbon nitride (a-CNx) as a saturable absorber (SA) in an all-fiber configuration. The a-CNx thin film was prepared using plasma-enhanced chemical vapor deposition. The laser operation showed remarkable stability, achieving a repetition rate of 57.99 kHz and a pulse duration of 1.36 μs at maximum input pump power. The peak power and pulse energy reached 100.56 mW and 136.77 nJ, respectively. The utilization of a-CNx as an SA offers potential benefits such as a simpler and more flexible cavity design, making it an attractive candidate for various applications, including material processing and medical laser equipment. This work contributes to the advancement of fiber lasers and expands the possibilities for utilizing carbon nitride-based SAs in practical laser systems.

“…There are several reports on conductivity in N-containing DLC (N-DLC) films. [13][14][15][16][17][18][19][20][21][22][23][24][25] In addition, this type of film improves friction characteristics and easily changes the optical band gap. Broitman et al fabricated an N-DLC film by unbalanced reactive magnetron sputtering.…”

Diamond-like carbon (DLC) films, which are amorphous carbon films, have been used as hard-coating films for protecting the surface of mechanical parts. Nitrogen-containing DLC (N-DLC) films are expected as conductive hard-coating materials. N-DLC films are expected in applications such as protective films for contact pins, which are used in the electrical check process of integrated circuit chips. In this study, N-DLC films are prepared using the T-shaped filtered arc deposition (T-FAD) method, and film properties are investigated. Film hardness and film density decreased when the N content increased in the films because the number of graphite structures in the DLC film increased as the N content increased. These trends are similar to the results of a previous study. The electrical resistivity of N-DLC films changed from 0.26 to 8.8 Ω cm with a change in the nanoindentation hardness from 17 to 27 GPa. The N-DLC films fabricated by the T-FAD method showed high mechanical hardness and low electrical resistivity.

“…Carbon nitride (g-C 3 N 4 ) has attracted an intense interest due to its particular electrical and optical properties. It constitutes a useful raw material for improving the mechanical and thermal properties of resulting products [14][15][16]. g-C 3 N 4 has been used in several fields such as biosensor [17,18], electrochemical agent [19,20], catalyst support [21], photocatalysts [22], and sorbent material [23].…”

at lower pressure. The adsorption isotherms show that the nanocomposite has a good CO 2 adsorption affinity compared to MIL-101. The best adsorption capacity is about 1.6 mmol g −1 obtained for the nanocomposite material which is two times higher than that of MIL-101, indicating strong interactions between CO 2 and MIL-101@g-C 3 N 4 . This difference in efficacy is mainly due to the presence of the amine groups dispersed in the nanocomposite. Finally, we have developed a simple route for the preparation of an effective and new adsorbent for the removal of CO 2 , which can be used as an excellent candidate for gas storage, catalysis, and adsorption.
