AMPLIFIER DEVICE AND AMPLIFIER MEDIUM

摘要

An amplifier medium (100) comprises a holey fiber (110) and a resin member (120). Light is transmitted through the holey fiber (110). The holey fiber (110) also has a winding part (111) wound in a three-dimensional manner. The winding part (111) is embedded in the resin member (120). Signal light is transmitted through the amplifier medium (100). Also, the excited light emitted from a light source is incident into the amplifier medium (100). The temperature of the amplifier medium (100) is adjusted along with the light source by a temperature adjusting part.
