Abstract
A short light pulse generating device includes a light pulse generating part, a first pulse compressing part, a second pulse compressing part, and an amplifying part. The light pulse generating part is configured to generate light pulses, the light pulse generating part being a super luminescent diode. The first pulse compressing part is configured to perform pulse compression based on saturable absorption on the light pulses generated by the light pulse generating part. The second pulse compressing part is configured to perform pulse compression based on group velocity dispersion compensation on the light pulses that underwent the pulse compression by the first pulse compressing part. The amplifying part is provided between the first pulse compressing part and the second pulse compressing part, and configured to amplify the light pulses that underwent the pulse compression by the first pulse compressing part.
