Light output apparatus and method

A light output apparatus comprising:

• a wideband pulse generator generating optical pulses by driving a wideband optical source with a pulse;
• a wavelength divider dividing the optical pulses for each wavelength;
• a dispersion time delay individually time-delaying of the wavelength divided optical pulses to allow the optical pulses to be dispersed in time domain;
• an optical multiplexer allowing the dispersed optical pulses to travel along one path;
• an optical amplifier amplifying output intensities of optical pulses output from the optical multiplexer;
• a pulse separator separating the optical pulses amplified by the optical amplifier for each corresponding wavelength;
• a time delaying unit delaying the optical pulses separated respectively for each wavelength and allowing the optical pulses to reach a combination point at an identical time;
• and
• a pulse combiner combining the optical pulses arrived at the combination point at the identical time.

A light output method comprising:

• dispersing generated optical pulses in time domain and allowing the dispersed optical pulses to travel along one path;
• amplifying output intensities of the optical pulses traveled along one path and separating the optical pulses for each corresponding wavelength;
• delaying individually the optical pulses separated for each wavelength and allowing the delayed optical pulses to reach a combination point at an identical time;
• and
• combining the optical pulses arrived at the combination point at the identical time and outputting a light having an output thereof increased.
