Abstract:Metal phosphates have emerged as low-cost inorganic materials suitable for high-performance energy storage and conversion devices. The photoluminescence properties of metal phosphates are now being explored for their optoelectronic applications. Among them, zinc phosphate is the composition of metal zinc and phosphoric acid. In this work, we have demonstrated the synthesis of zinc phosphate by the solvothermal method and its potential as a saturable absorber (SA) to generate a tunable mode-locked laser at 1.9 … Show more
“…Laser spot welding also benefits from nanosecond pulse fiber lasers as they refine grains in the fusion zone and enhance the mechanical properties of welded specimens [5]. The study of nanosecond dark pulses has emerged as a captivating area of research within the realms of ultrafast photonics and laser technology due to their distinctive characteristics that render them highly desirable for applications like laser mode-locking, pulse shaping, and optical signal processing [6,7].…”
Molybdenum gallium carbide (Mo2Ga2C), a material belongs to MAX phase group, has garnered significant interest in a wide range of scientific field, including material science, engineering, and laser physics. It is chemically and structurally promising since it exhibits a low shear modulus, superconducting behaviour, and high mechanical stability. Here, we prepared a saturable absorber (SA) based on Mo2Ga2C coated D-shape fiber using solution casting technique. It exhibits outstanding saturable absorption of 7.2%, allowing it to generate dark pulse laser in an erbium-doped fiber laser cavity. We analyzed the laser's performance and obtained a dark pulse with a pulse energy, peak power, and average output power of 3.9 nJ, 27.5 mW, and 7.3 mW, respectively. This foundational work may introduce a new material as an alternative SA device in fiber laser cavity.
