High-power mid-infrared frequency comb source based on a femtosecond Er:fiber oscillator.

We report on a high-power mid-infrared (MIR) frequency comb source based on a femtosecond (fs) Er:fiber oscillator with a stabilized repetition rate of 250 MHz. The MIR frequency comb is produced through difference frequency generation in a periodically poled MgO-doped lithium niobate crystal. The output power is about 120 mW, with a pulse duration of about 80 fs and spectrum coverage from 2.

0.7W all-fiber Erbium oscillator generating 64 fs wave breaking-free pulses.

We report on the generation of wave breaking-free pulses from a passively mode-locked all-fiber Erbium oscillator at 1.55 microm pumped by a Raman fiber assembly operating at 1.48 microm.

Stable sub-85 fs passively mode-locked Erbiumfiber oscillator with tunable repetition rate.

We present a sub-85 fs self-starting stretched-pulse passively mode-locked Erbium-fiber oscillator in a sigma setup with tunable repetition rate. The sigma cavity included a movable mirror enabling a tunable pulse repetition rate variation of +/- 1 % from 55.3 MHz to 56.

Phase-locked carrier-envelope-offset frequency at 1560 nm.

We report on the measurement of an Erbium-fiber oscillator's carrier-envelope-offset frequency using an extruded SF6 photonic crystal fiber for the generation of a more than two octave-spanning supercontinuum from 400 nm to beyond 1750 nm. A modified type of f-2f-interferometer was employed, beating the frequency doubled input signal of the fiber oscillator with the supercontinuum to generate the carrier-envelope-offset beat. Controlling the fiber oscillator's pump power with an electronic feedback loop, we phase-locked the carrier-envelope-offset frequency to an external reference source.

Supercontinuum generation with 200 pJ laser pulses in an extruded SF6 fiber at 1560 nm.

We report an all-fiber diode-pumped Erbium-fiber oscillator-amplifier system as a source for supercontinuum generation in a photonic crystal fiber at 1560 nm. The passively mode-locked oscillator-amplifier system provides linearly polarized output pulses of 60 fs and an average output power of 59 mW at a repetition rate of 59.1 MHz.
