摘　　要：Numerical simulation is described which estimates the performance of thulium sensitized holmium doped CW fluoride fiber laser at 2.04 μm for both core and cladding pumped. This model takes into account the mechanisms of cross relaxation and energy transfer to describe the laser operation. A subroutine program for calculating the absorption rate of cladding pumped scheme is included in the model. The losses of signal and pump light along the fiber have been taken into account. The test of cladding pumped scheme program shows good agreement with the experimental result. The experimental results of core pumping Tm Ho doped fiber laser in fluoride host are compared with the present model, and shows a good agreement with calculations. This model also provides data of the optimum parameters for the configuration of the efficient cladding pumped Tm Ho fluoride laser systems.报导芯泵浦和包层泵浦两种情况下，工作于２．０４μｍ的Ｔｍ－Ｈｏ双掺氟基光纤激光器的数值模拟．数值模型考虑了交叉弛豫和能量转移过程对激光运转的影响，并考虑了沿光纤传输过程的信号和泵光损耗．模型用一个子程序来模拟包层泵浦的吸收过程并给出了与实验符合的结果，与芯泵浦Ｔｍ－Ｈｏ双掺光纤激光器的实验结果比较说明理论计算和实验结果符合得相当好，并在此基础上为建造新的包层泵浦高效Ｔｍ－Ｈｏ氟基光纤激光器提供了优化参数．
