通过比较在相同发热功率和散热条件下双包层光子晶体光纤和传统双包层光纤的温度分布，考察了双包层光子晶体光纤的散热能力.数值研究结果表明：双包层光子晶体光纤的散热能力要弱于后者;但从总体来看,传统双包层光纤和光子晶体光纤的热性能对激光器的激光性能的影响是近乎相同的.

The heat dissipation ability of double-cladding photonic crystal fiber was studied by comparing the temperature distribution in the conventional double-cladding fiber with that in the double-cladding photonic crystal fiber under the same conditions.The numerical results show that the heat dissipation ability of double-cladding photonic crystal is weaker than the conventional double-cladding fiber′s.However,in general,the influences of the heat properties of the conventional double-cladding fiber and the double-cladding photonic crystal fiber on the laser property are almost the same.
