Description
Summary:•Detailed study of self-terminating Ba+ laser is presented.•Application of eptron significantly improves Ba+ laser output characteristics.•Hydrogen effect for metal vapor ion lasers is demonstrated. Experimental results of the laser operating on the barium ion self-terminating transition 6p2P3/2o - 5d2D5/2 at λ=614.2 nm investigations are presented. Through a series of tests, we demonstrated a significant improvement of the output characteristics of this laser by employing (i) a novel high-voltage nanosecond switch capable to operate at high pulse repetition frequency (more than 50 kHz), and (ii) hydrogen addition to the active medium. Achieved steady-state average output power in the burst-mode operation amounted to 125 mW with laser pulse duration of ≈5 ns at half-maximum.
