AI Article Synopsis
- A new type of ferromagnetic insulator was studied for its nonlinear optical absorption properties and potential applications in ultrafast modulation.
- Saturable absorbers were created with a modulation depth of 9.7% and a saturable intensity of 3.5, leading to successful soliton operations at a pump power of 120 mW.
- Experimental results showed that this material can effectively serve as a saturable absorber for generating ultrafast pulse lasers with a pulse duration of approximately 1.33 µs and a high signal-to-noise ratio of 50 dB.
Article Abstract
In our work, a new-type, to the best of our knowledge, ferromagnetic insulator and its nonlinear optical absorption characteristics and related ultrafast modulation applications were investigated. saturable absorbers (SAs) with a modulation depth and a saturable intensity of 9.7% and 3.5/ were fabricated. By adjusting the pump power to 120 mW and optimizing the polarization state, traditional soliton operations were obtained successfully; the corresponding duration of pulse and the fundamental repetition rate were ∼1.33 and 6.70 MHz, and the signal-to-noise ratio was 50 dB. The experimental results reveal that with excellent saturable absorption characteristics can be used as a SA to obtain ultrafast pulse lasers.
