摘要
The invention refers to a method for operating an amplifier with a first amplifier stage (A1) and a second amplifier stage (A2), pumped by a single pump light source (11) generating a primary pump signal (S PUMP ), which is split into first pump signal (S1) and a second pump signal (S2) according to a variable splitting factor (±) for pumping the first amplifier stage (A1) and the second amplifier stage (A2) respectively. The splitting factor (±) is varied to achieve an optimized noise figure.
