The presented theoretical model for a mode-locked Nd-glass laser
simultaneously takes into account dynamics of the mode-locking dye,
amplification saturation and radiation background. A systematic
variation of laser parameters gives insight into the pulse
formation process and allows to improve the laser design. The
calculations show that it should be possible to decrease
considerably the duration of light pulses of a mode-locked Nd-glass
laser. Using a new mode-locking dye with a switching time of
τ=2.7×10−12 s we obtained stable laser operation and a pulse
duration of 1.7×10−12s.
