Abstract
A light emitting device has: a dispersion light source wherein a plurality of semiconductor laser bars are arranged; and a drive circuit which makes the dispersion light source output at least one pulsed beam by supplying at least one drive pulse to the dispersion light source. In the dispersion light source, a plurality of semiconductor laser bars are arranged on a base, and furthermore, heat dissipating plates are arranged between the semiconductor laser bars. The pulse width of the pulsed beam outputted from the dispersion light source is longer than 1 femtosecond but shorter than 0.25 second, and the energy of the single pulsed beam is less than 66.8 μ[J].
