  • METHOD AND APPARATUS FOR COOLING A FIBER LASER OR AMPLIFIER
    Publication number: 20120085518
    Abstract: A system and method for cooling an optical fiber includes a flexible heat sink member, a heat pipe evaporator, and a thermal storage medium. The flexible heat sink member is in thermal contact with the optical fiber. The heat pipe evaporator is configured to dissipate heat from the optical fiber. The thermal storage medium is in thermal contact with the flexible heat sink member and the heat pipe evaporator. The flexible heat sink member is configured to compensate for any mismatch in coefficient of thermal expansion between material of the optical fiber and material of the flexible heat sink member so as to provide radial compliance and to maintain direct thermal contact between the optical fiber and the flexible heat sink member.
