摘要

摘要本工作证明了三氧化钨/聚二甲基硅氧烷纳米复合材料可饱和吸收体（WO3/PDMS-SA）在网络反常色散中实现了常规锁模孤子（CS）和类噪声脉冲（NLP）激光的产生。970.0 CS体制的转换形成 fs脉冲持续时间至182.0的NLP状态 fs相干尖峰65.3 ps底座是通过改变泵功率来实现的。脉冲激光器表现出良好的稳定性，分别为50.76和49.82 9.09时的dB信噪比 MHz基本重复率和CS和NLP系统稳定性测试期间的微小变化。这项工作表达了WO3/PDMS-SA在使用固定腔配置实现各种类型的锁模脉冲现象方面的可行性，该固定腔配置可认为有益于紧凑的两用激光系统。

Tungsten trioxide nanocomposite for conventional soliton and noise-like pulse generation in anomalous dispersion laser cavity

Abstract This work demonstrates the employment of tungsten trioxide/polydimethylsiloxane nanocomposite saturable absorber (WO3/PDMS-SA) in realizing mode-locked conventional soliton (CS) and noise-like pulse (NLP) laser generation in net anomalous dispersion. The switching formation from CS regime of 970.0 fs pulse duration to NLP regime of 182.0 fs coherent spike with 65.3 ps pedestal was achieved by varying its pump power. The pulse laser exhibited good stability of 50.76 and 49.82 dB signal-to-noise ratio at 9.09 MHz fundamental repetition rate and trivial variation during stability test for CS and NLP regime, respectively. This work expresses the feasibility of WO3/PDMS-SA in attaining various types of mode-locked pulse phenomena using a fixed cavity configuration conceivably beneficial for compact dual-purpose laser systems.

期刊介绍： The bimonthly journal Nanotechnology Reviews provides a platform for scientists and engineers of all involved disciplines to exchange important recent research on fundamental as well as applied aspects. While expert reviews provide a state of the art assessment on a specific topic, research highlight contributions present most recent and novel findings. In addition to technical contributions, Nanotechnology Reviews publishes articles on implications of nanotechnology for society, environment, education, intellectual property, industry, and politics.
