High Power Coupled Fel Oscillators for the Generation of High Repetition Rate Ultrashort Mid-ir Pulses
نویسنده
چکیده
100-200 MeV range ERL driven high gain FEL oscillators generating few cycle short, high intensity midIR pulses with tens of MHz repetition rates might become attractive tools in various strong field applications. In a recent study a mode-locked, coupled FEL oscillator scheme has been presented to generate multi-mJ level, ultra-short (<10 cycles) output pulses tunable within the entire IR region. The current work elaborates on an improved FEL oscillator scheme that can cope with the high power levels accumulated within the coupled cavity while operating unidirectionally, eliminating the feedback in the reverse direction. The various operational regimes of the coupled laser system are discussed.

Progress Report on Development of Novel Ultrafast Mid- Ir Laser System*
Of particular interest to X-ray FEL light source facilities is Enhanced Self-Amplified Spontaneous Emission (ESASE) technique. Such a technique requires an ultrafast (20-50 fs) high peak power, high repetition rate reliable laser systems working in the mid-IR range of spectrum (2μm or more). The approach of this proposed work is to design a novel Ultrafast Mid-IR Laser System based on optical p...
متن کاملTemporal characterization of mid-IR free-electron-laser pulses by frequency-resolved optical gating.
We performed what we believe are the first practical full-temporal-characterization measurements of ultrashort pulses from a free-electron laser (FEL). Second-harmonic-generation frequency-resolved optical gating (FROG) was used to measure a train of mid-IR pulses distorted by a saturated water-vapor absorption line and showing free-induction decay. The measured direction of time was unambiguou...

Various scientific and industrial laser applications profit from the latest progress of directly diode pumped high-power femtosecond oscillators, in particular applications such as laser micromachining, nonlinear spectroscopy, or laser surgery. These oscillators provide pulse energies in the microjoule regime at 100 kHz to megahertz repetition rates, replacing complex and expensive chirpedpulse...
متن کاملBroadly tunable femtosecond pulse generation in the near and mid-infrared.
High-repetition-rate (80-MHz) femtosecond infrared pulses are generated by difference frequency mixing (DFM) a femtosecond Ti:sapphire laser with a phase-locked synchronized cw mode-locked Nd:YAG picosecond laser. This DFM scheme is of particular interest for generating ultrashort near-IR pulses (~10 fs) because group velocity mismatch with a pump pulse can be ignored. The simplicity and the br...
متن کاملFiber-laser-pumped, high-energy, mid-IR, picosecond optical parametric oscillator with a high-harmonic cavity.
We demonstrate the generation of high-energy, mid-IR, picosecond pulses in a high-harmonic-cavity optical parametric oscillator (OPO) that has a relatively compact cavity with a length that is a small fraction of that required to match the pump repetition rate. The OPO, based on an MgO-doped periodically poled LiNbO3 crystal, is pumped by a fiber master-oscillator-power-amplifier system employi...
