Description/Abstract
In recent years the combination of laser-diode pumping with the technique of additive-pulse mode-locking (APM) has permitted the development of highly efficient, stable, compact sources of mode-locked pulses in the picosecond regime. We report the development of an APM laser-diode-pumped NdxLa(1-x)MgAl(11)O(19) (Nd:LMA) laser capable of generating pulses as short as 400 fs. Nd:LMA is a laser material whose broad absorption around 800 nm and broad fluorescence linewidth (~1.3 THz) centered at 1054 nm make it an ideal candidate for both laser-diode pumping and short-pulse generation by means of mode locking. Such a mode-locked source would make an excellent oscillator for high-power Nd:glass amplifier systems. Furthermore, Nd:LMA does not exhibit the catastrophic thermal problems of the Nd:glass laser, which is clearly another candidate for subpicosecond pulse generation at this wavelength.
