Sub-20-fs pulse generation in the ultraviolet

Not Accessible

Your library or personal account may give you access

Abstract

In this talk, we report the generation of ultrashort ultraviolet (uv) pulses using nonresonant third-harmonic conversion of a 22-fs driving pulse1 in a gas. In order to generate ultrafast uv pulses via harmonic generation, it is preferable to use gases rather than crystals such as BBO (beta-barium borate). This is because complications such as finite phase-matching bandwidths and temporal walk-off, which place limits on the uv pulsewidth, can be avoided by using gases.
