ERBIUM DOPED CRYSTAL AMPLIFIER

摘要

The present invention is an amplifier (18) which includes a signal source (11) transmitting a signal (12), which includes a signal portion in the L-band. The signal first passes into a first signal manipulator (16) which is one or more collimators and/or concentrators, and can include dichroics or optical manipulators. Input pump radiation (15) is aligned to overlap the signal. From the first signal manipulator, the signal and pump light intersect an erbium doped crystal and the signal is amplified (15).
