A Tale of Two Tantalum Borides as Potential Saturable Absorbers for Q-Switched Fiber Lasers

Hattori, Haroldo T.; As'ham, Khalil; Haque, Ahasanul; Li, Ziyuan; Olbricht, Benjamin C


In this paper, we analyze the performance of two tantalum-based boride (TaB and TaB 2 ) microparticles as potential saturable absorbers for high-power fiber lasers. Both materials are ultrahigh temperature ceramics with melting points above 3000 °C, but with different crystalline structures: TaB has an orthorhombic structure (nearly isotropic), whereas TaB 2 has a hexagonal structure (uniaxial, anisotropic). Despite their different crystalline structures, the microparticles have a similar low...[Show more]
