Abstract
In an example, an apparatus to tandem pump a fiber laser or fiber amplifier may include a combiner; a power amplifier or a power oscillator, or a combination thereof, coupled to an output of the combiner; a seed laser to output light to the power amplifier or the power oscillator, or the combination thereof, via the combiner; and a tandem pump to generate light of a pump source signal, wherein the light of the pump source signal is output to the combiner to cladding pump the power amplifier or the power oscillator, or the combination thereof. Other embodiments may be disclosed and/or claimed.
Claims12
An apparatus, comprising:
- a combiner;
- a power amplifier or a power oscillator, or a combination thereof, coupled to an output of the combiner;
- a seed laser to output light to the power amplifier or the power oscillator, or the combination thereof, via the combiner;
- and
- a tandem pump to generate light of a pump source signal, wherein the light of the pump source signal is output to the combiner to cladding pump the power amplifier or the power oscillator, or the combination thereof;
- wherein the tandem pump is end-pumped using at least one diode pump, and wherein quantum defect heating inside the tandem pump is 7% or less based on a correspondence of a center wavelength of an output of the at least one diode pump to a center wavelength of an output of a fiber laser oscillator of the tandem pump.
