Abstract

AbstractA 1089 nm Q‐switched laser has been successfully developed by using a neodymium‐doped fiber (NDF) as a gain medium and tin oxide (SnO2) material as a saturable absorber (SA). The SnO2 SA was obtained by embedding the compound into a polyvinyl alcohol (PVA) host polymer so that it can be easily integrated into an NDF laser (NDFL) configuration to modulate the cavity loss for pulsing operation. The laser output pulse duration and repetition rate changed from 6.7 to 4.2 µs and from 55.8 to 72.5 kHz, respectively, when the 808 nm pumping power increased from 160.0 to 252.7 mW. The laser exhibited a stable output since we recorded a signal‐to‐background noise ratio of 46.4 dB. We believe that this work is the first to address SnO2 as SA in an NDFL cavity.
