Title:
PULSED LIGHT SOURCE AND PULSED LIGHT GENERATING METHOD
Document Type and Number:
WIPO Patent Application WO/2017/204299
Kind Code:
A1
Abstract:
This pulsed light source (10) is provided with: a pump light source (100); and a resonator (200). The resonator (200) has a rare-earth-doped fiber amplifier (REDFA) (220). The pump light source (100) provides pump light to the REDFA (220). The pump light is modulated by a modulation signal which has a modulation frequency fmod almost equivalent to an integer multiple of a fundamental resonance frequency f1 of the resonator (200). In detail, the modulation frequency fmod is a frequency of 95% to 105% of the integer multiple of the fundamental resonance frequency f1 of the resonator (200).
