title: Widely tunable 11 GHz femtosecond fiber laser based on a nonmode-locked source.
abstract: An 11 GHz fiber laser built on a modulated cw platform is described and characterized. This compact, vibration-insensitive, fiber-based system can be operated at wavelengths compatible with high-energy fiber technology, is driven by an RF signal directly, and is tunable over a wide range of drive frequencies. The demonstration system when operated at 1040 nm is capable of 50 ns bursts of 575 micropulses produced at a macropulse rate of 83 kHz where the macropulse and micropulse energies are 1.8 and 3.2 nJ, respectively. Micropulse durations of 850 fs are demonstrated. Extensions to shorter duration are discussed.
