qcl的音标

The doping concentration in the active region has great effect on the waveguide property. With the increasing of doping concentration, the waveguide loss, threshold gain and current density of THz QCL increase, the confinement factor decrease. 3.

结果表明，随着有源区掺杂浓度的提高，波导损耗增加，阈值电流增加，波导限制因子降低。

This driver system includes a current driver control section and a temperature control section. Finally, the performance tests of this drive power system for QCL are done. The experimental results showed that the technical qualifications have met the design requirements expected.
