FIBRE MASTER OSCILLATOR POWER AMPLIFIER (MOPA) WITH AMPLIFYING TRANSPORT FIBRE

摘要

Frequency-multiplied, Fiber master oscillator power amplifier (MOPA) apparatus includes one enclosure (12) containing a master oscillator and fiber amplifier stages and another enclosure (22) containing frequency-multiplying stages. Radiation is transmitted between the enclosures by a transport fiber in a flexible jacket (14) or enclosure. The transport fiber functions additionally as a power amplifier fiber, and amplifies the radiation while transporting the radiation between the enclosures. The amplifying transport fiber is energized by diode- lasers in the enclosure (12) containing the master oscillator and fiber amplifiers.
