Low repetition rate 343 nm passively Q-switched solid-state laser for time-resolved fluorescence spectroscopy.

open access: yesOptics Express, 2018
We demonstrate a low-cost 343 nm solid-state laser delivering up to 20 µJ per pulse, with a pulse width of 2.3 ns at a repetition rate of 100 Hz. The 343 nm is obtained through a third harmonic generation of a passively Q-switched 1030 nm Yb:YAG laser ...
