Beschreibung
Zusammenfassung:	A light source is provided with: a seed light source that outputs incoherent seed light having a predetermined frequency band; and a booster amplifier as a semiconductor optical amplifier that optically amplifies the seed light input from the first end face and outputs the amplified light from the second end face, the booster amplifier setting a product (nL) of a refractive index (n) and a chip length (L) such that relative intensity noise (RIN) and pulsation in the amplified light are simultaneously suppressed. 光源具备：种子光源，输出具有给定的频带的非相干的种子光；以及作为半导体光放大器的助推放大器，对从第一端面输入的所述种子光进行光放大，并作为放大光从第二端面输出，所述助推放大器设定折射率(n)与芯片长度(L)之积即(nL)，以使得在所述放大光中相对强度噪声(RIN)以及脉动被同时抑制。
