TiB₂ nanoparticles with a broadband nonlinear response for ultrafast pulse generation

Abstract

Titanium boride (TiB2), as a kind of metal boride materials, has exhibited extraordinary physical and chemical properties. However, few studies have been dedicated to the potentials in nonlinear optics and...

A Watt-Level Pulsed Er:Lu2O3 Laser Based on a TiB2 Saturable Absorber

“…Thus, the material exhibits high stability, high melting temperature, hydrolysis resistance, antioxidant capacity, and high LDT. Employed as an SA in a fiber laser, the TiB 2 nanosheet has delivered ultrafast pulses with a pulse duration of 596 fs and a peak power of ~2 kW at emitting at 1559 nm [ 18 ]. The above property and result show that a mid-infrared pulsed laser with watt-level output power is worth being expected with TiB 2 .…”
