An alternative pump scheme, named indirect pump one is proposed to clarify its own feasibility. The high device performances of 8 mu m quantum cascade lasers with cavity lengths of 4 mm and 1.5 mm are demonstrated: low threshold current densities of 2.7 and 3.3 kA/cm(2) and maximum output powers of 362 and 50 mW at room temperature, and high T-0-values of 243 and 303 K around room temperature. The higher T-0-value, 303 K is the highest record ever reported with quantum cascade lasers. The high stability for temperature changes is interpreted in terms of the indirect pumping model.
