论文摘要
Gold nanorods (GNRs) with two different aspect ratios were successfully utilized as saturable absorbers (SAs) in passively Q-switched Nd:LLF laser emitting at 1.34 μm. Based on the GNRs with an aspect ratio of 5, a maximum output power of 1.432 W was achieved, and the narrowest pulse width was 328 ns with a repetition rate of 200 kHz. But in the case of the GNRs with the aspect ratio of 8, a maximum output power of 1.247 W was achieved, and the narrowest pulse width was 271 ns with a repetition rate of 218 kHz. Our experimental results reveal that the aspect ratios of GNRs have different saturable absorption effects at a specific wavelength. In other words, for passively Q-switched lasers at a given wavelength, we are able to select the most suitable GNRs as an SA by changing their aspect ratio.
