Abstract: We employ a broadband Ti:sapphire femtosecond oscillator to simultaneously launch two localized surface plasmon modes in rectangular plasmonic nanoholes. The resonant frequencies of these two modes match well with our laser spectrum. As a result, the nanoholes do not only efficiently boost the third harmonic radiation intensity, but also significantly broaden the harmonic's bandwidth, producing a nanoscale deep-ultraviolet light source in the range of 240 to 300 nm. Due to the involvement of two modes, the third harmonic beam becomes elliptically polarized and reaches its maximum intensity when laser polarization direction is 60° with respect to the long edges, rather than the commonly used 90°.
