Abstract
A light source for emitting a pulsed laser beam having an ultrashort pulse width and a voltage detector including the light source therein. The light source includes a laser driving unit for driving the laser source to output the pulsed laser beam while the intensity of the pulsed laser beam is stabilized. A chirp compensator is also included to compensate for a chirp in the pulsed laser beam. A wavelength selector is used to extract light having a desired wavelength from the pulsed laser beam, thereby obtaining a pulsed laser beam having an ultrashort pulse width and a desired narrow spectral band width.
