All-Optical 3R Regeneration Using Fiber Optical Parametric Oscillator and Amplifier [PDF]
National Fiber Optic Engineers Conference, 2012 We demonstrate an all-optical wavelength-tunable 3R regenerator based on fiber optical parametric oscillator and amplifier. Regenerated signal with a power penalty of 0.1 dB versus back-to-back at 10-9 BER can be obtained.

Wide-Band Generation of Picosecond Pulse Using Fiber Optical Parametric Amplifier and Oscillator [PDF]
IEEE Journal of Quantum Electronics, 2009 We first demonstrate a wideband generation of picosecond pulse using fiber optical parametric amplifier (FOPA). High quality pulse is generated at 85 nm away from the pump with pulsewidth narrower than that of the pump. We then explore fiber optical parametric oscillator (FOPO) configuration which has the advantage of eliminating the need of seeding ...

A 20 W, Less-Than-1-kHz Linewidth Linearly Polarized All-Fiber Laser
Applied Sciences, 2018 We report a continuous-wave high-output power and narrow-linewidth all-fiber laser at 1550 nm with the master oscillator power amplifier (MOPA) configuration. An all-fiber distributed feedback seed laser was boosted by three cascaded fiber amplifiers. In

A Comparison of Laser and Microwave Approaches to CW Beamed Energy Launch [PDF]
, 2006 One approach to beamed energy propulsion uses a solid heat exchanger to absorb energy from a distant source and transfer it to a working fluid. Systems of this type can be designed using either microwave or laser sources.
