Abstract

Nowadays, the development of broadband ultrafast saturable absorbers (SAs) based on carbon nanostructures (e.g., graphene, SWCNTs) and 2D-materials (e.g., MoS2, topological insulators) for passive Q-switching (PQS) and mode-locking (ML) of near-IR lasers (1-2 μm) is attracting a tremendous interest [1]. For PQS, such absorbers can be integrated into compact bulk (microchip) and waveguide lasers providing ns-long pulses at high repetition rates (up to few MHz). Zinc oxide (ZnO) nanostructures exhibit outstanding physical properties and they are used in various photonic applications. In the present work, we demonstrate the potential of ZnO nanorods (NRs) for broadband SAs for near-IR lasers.
