| 1. A fiber laser system comprising:
fiber including dysprosium (Dy);
a pump light source disposed at a side of the fiber and emitting pump light having a wavelength exciting electrons of the
dysprosium (Dy) from a ground energy level 6H15/2 to an energy level 6H11/2;
a first reflection member, disposed between the fiber and the pump light source, transmitting the pump light, and reflecting
first lasing light having a first wavelength; and
a second reflection member, disposed at a side opposite to the pump light source with respect to the fiber, and transmitting
a portion of the first lasing light.
