Frequency-converted Fiber-MOPA

摘要

Fundamental-wavelength radiation from a fiber MOPA 12 amplified in an active optical fiber 14. The active fiber 14 is terminated at a distal end 14D by an endcap 16 having an exit-face 18 from which fundamental radiation is delivered. The endcap 16 is hermetically sealed to a wall of an enclosure 30 housing frequency conversion elements. Pump-radiation for the active fiber 14 is fiber coupled into the active fiber 14 at a proximal end thereof.
