Abstract

The laser-diode-pumped, actively mode-locked Nd:glass laser has recently been shown to be a good source of picosecond pulses.^1,2 Subpicosecond pulses have been obtained by using self-starting additive pulse mode-locking (ARM),³ where the Nd:glass laser was pumped with a krypton laser.⁴ An intensity threshold for the onset of self-starting ARM⁵ indicates the need to develop high-power, high-slope efficiency, laser-diode-pumped Nd:glass lasers, if self-starting ARM is to be achieved in this all solid-state system.
