摘要：

<p>There is disclosed a reshaping device for optical short pulses to effectively performing reshaping of and eliminating noise from an optical short pulse of a pulse width of pico second order less than a carrier life time. Input optical short pulses are applied to a saturable absorption element (11), while an assist light (2,4) of a wavelength longer than that of the input optical signal pulses is also applied to the saturable absorption element (11) to accelerate, by stimulated emission, recombination of excited electrons and holes produced in the saturable absorption element in response to the input optical signal pulses (1), so that the input optical signal pulses reshaped are derived from the saturable absorption element. <IMAGE></p>
