Fiber laser pump reflector
A pump reflector (10) for efficiently recycling unabsorbed pump radiation in a diode-pumped fiber laser includes a core (12) for guiding a laser beam, a pump cladding (14), and a tapered capillary tube (16). Pump radiation is adiabatically guided in the tapered capillary tube (16), which includes a...

| Zusammenfassung: | A pump reflector (10) for efficiently recycling unabsorbed pump radiation in a diode-pumped fiber laser includes a core (12) for guiding a laser beam, a pump cladding (14), and a tapered capillary tube (16). Pump radiation is adiabatically guided in the tapered capillary tube (16), which includes a mirror (28) that is reflective for the pump radiation. The pump reflector (10) may be packaged as a fiber component for copropagating or counter-propagating fiber laser amplifiers and resonators. |
