Abstract:
A pump laser package may include an input fiber to send signal light on a first optical path. A first lens may be arranged on the first optical path. The pump laser package may include a source to send pump light on a second optical path. A second lens and a negative lens may be arranged on the second optical path. The first lens and the negative lens may be arranged to create a virtual image associated with the pump light. The pump laser package may include an output fiber on a third optical path. The first lens may be arranged on the third optical path. The pump laser package may include a combiner to receive the signal light on the first optical path, receive the pump light on the second optical path, and send the signal light and the pump light on the third optical path.
