We report a high power diode-pumped mid-IR fiber amplifier at 2.7 mum. 4.6 W amplified signal was obtained for an input signal of 110 mW, corresponding to a net gain of 16.2 dB.
Benefits provided by a new high-power and low-noise laser for efficient first-order Raman co-pumping are experimentally investigated. 8 times 10 Gb/s WDM channels have been successfully transmitted over 70dB of standard single-mode fiber with realistic system margins.
A Ti:sapphire regenerative ring amplifier is developed. The power of 40 W before compression and 26 W after compression are achieved at 10 kHz repetition rate. Thermal distortion of a compressor grating is reduced by air flow cooling.
We evaluate the chaotic behavior and electronic control in ASE recirculating clamped ring network. Unstable network operating conditions are addressed using a newly developed analytical model able to describe dynamic behavior.
We study the power dependence of the back reflection from microsphere resonators. Experimental results are compared with theoretical models. An EDFA (Erbium Doped Fiber Amplifier) based laser with a microsphere mirror is demonstrated.
Broadband pulse amplification is demonstrated with a fiber laser pumped high repetition rate optical parametric amplifier. Subsequent pulse compression in a prism sequence resulted in 46 fs pulses with peak powers above 10 MW.
