Ultrafast laser pulse created by golden nanoparticles: The creation of a fast, tunable and stable nanoparticle-array laser is a stepping stone to affordable and efficient sensing and switching

The creation of a fast, tunable and stable nanoparticle-array laser is a stepping stone to affordable and efficient sensing and switching. New study shows that organic dye material combined with metallic nanostructures can provide ultrafast lasing dynamics with short and rapidly appearing laser pulses.
