1. A laser oscillating apparatus comprising:

  • an optical resonator comprising at least a laser crystal and an output mirror;

    a laser beam source for pumping said optical resonator, said laser beam source having associated therewith a fluorescence lifetime τ

    FL ; and

    pulse driving means for driving said laser beam source, said pulse driving means producing a series of pulses with a period T, each of said pulses having a pulse width of τ

    ;

    wherein the fluorescence lifetime τ

    FL, the period T, and the pulse width τ

    are related such that τ

    FL >

    T-τ
