Article Abstract
Herein, we present aN Er-doped all-fiber laser with BiVO as the saturable absorber (SA). To illustrate the nonlinear optical response, a two-dimensional model of monoclinic and its electronic structure was calculated. The nonlinear absorption properties were evaluated utilizing the Z-scan technique, and a saturable absorber was fabricated for integration into a fiber laser, resulting in a stable Q-switched output. At a maximum pump power of 600 mW, the fiber laser achieved an average output power of 25.23 mW and a pulse energy of 330.76 nJ. This research confirms that BiVO material exhibits outstanding nonlinear optical characteristics, thereby broadening its scope of application in the realm of ultrafast pulsed fiber lasers.

A series of unsymmetrically substituted BODIPY dyes featuring fused benzo- or naphtho-fragments on one pyrrolic unit were synthesized from the corresponding pyrrolic precursors. The synthetic route was optimized using a modular approach based on the condensation of formylpyrroles with alkylpyrroles, enabling the identification of precursor combinations that minimize byproduct formation and improve preparative yields. The resulting benzo- and naphtho-fused BODIPYs display intense fluorescence in the red region, with emission maxima spanning 590-680 nm and fluorescence quantum yields ranging from 0.

Incorporating atomically thin two-dimensional (2D) materials with optical fibers expands their potential for optoelectronic applications. Recent advancements in chemical vapor deposition have enabled the batch production of these hybrid fibers, paving the way for practical implementation. However, their functionality remains constrained by the integration of a single 2D material, restricting their versatile performance.

Soliton propagation of laser radiation in various nonlinear media is of great importance because of its numerous applications. Active periodic structures with parity-time symmetry provide the possibility for the solitons generation due to the balance of energy gain and loss. In the present paper, we derive an approximate analytical soliton solution to a model of two-color laser radiation propagation in an active periodic structure.

Nonlinear optical (NLO) crystals capable of expanding the spectral region of solid-state are of great importance for many high-tech applications, yet their rational structure design remains a great challenge because of the conflicting property requirements among second harmonic generation (SHG) response, ultraviolet (UV) cut-off edge, and birefringence. Herein, based on the chemical disubstitution of the classic NLO crystal SrBeBO (SBBO), , substituting [BO] triangles with larger π-conjugated [BO] groups and substituting high-toxic [BeO] tetrahedra with environment-friendly [AlO] tetrahedra, a new high-performance aluminoborate NLO crystal, BaAlBO, has been successfully designed and synthesized. The theoretical calculations and optical property measurements indicate that BaAlBO exhibits not only the largest SHG response among the reported aluminoborates (2.

In this work, we report a theoretical investigation of the third-order nonlinear optical properties of the metronidazolium-picrate salt. The effects of the crystal environment are accounted for by the Iterative Charge Embedding approach, and the electronic calculations are carried out at the DFT (CAM-B3LYP/6-311++G-(d,p)) level. Furthermore, we use the results to parametrize a cavity Quantum Electrodynamics model for a quantum memory based on the Off-Resonant Cascaded Absorption protocol.
