High-repetition-rate coherent femtosecond pulse amplification with an external passive optical cavity.
نویسندگان
چکیده
We demonstrate a general technique for enhancement of femtosecond pulses from a pulse train through their coherent buildup inside a high-finesse cavity. Periodic extraction of the intracavity pulse by means of a fast switch provides a net energy gain of 42 to >70 times for 38-58-fs pulse durations. Starting with an actively stabilized but otherwise standard mode-locked laser system, we demonstrate pulses of >200-nJ energy.

Femtosecond pulse amplification by coherent addition in a passive optical cavity.
By simultaneously controlling repetition and carrier frequencies, one can achieve the phase coherent superposition of a collection of successive pulses from a mode-locked laser. An optical cavity can be used for coherent delay and constructive interference of sequential pulses until a cavity dump is enabled to switch out the amplified pulse. This approach will lead to an effective amplification...
متن کاملPicosecond-pulse amplification with an external passive optical cavity.
We experimentally demonstrate the amplification of picosecond pulses at high repetition rates through the coherent addition of successive pulses of a mode-locked pulse train in a high-finesse optical cavity equipped with cavity dumping. Amplification greater than 30 times is obtained at a repetition rate of 253 kHz, boosting the 5.3-nJ pulses from a commercial mode-locked picosecond Ti:sapphire...
متن کاملPhase-coherent frequency combs in the vacuum ultraviolet via high-harmonic generation inside a femtosecond enhancement cavity.
We demonstrate the generation of phase-coherent frequency combs in the vacuum utraviolet spectral region. The output from a mode-locked laser is stabilized to a femtosecond enhancement cavity with a gas jet at the intracavity focus. The resulting high-peak power of the intracavity pulse enables efficient high-harmonic generation by utilizing the full repetition rate of the laser. Optical-hetero...
متن کاملHigh Intensity Femtosecond Enhancement
To produce extreme ultraviolet radiation via high harmonic generation (HHG) in rare gases, light intensities in excess of 1014 W/cm 2 are required. Usually such high intensity are obtained by parametric amplification of laser pulses, which in turn reduces the pulse repetition rate to a few kHz. Given that the HHG process is inherently inefficient, with conversion ratios less than 10-5, only a s...
متن کاملHigh Energy/High Repetition Rate Laser Pulses from Yb Based Solid State Oscillators with Cavity-Dumping and Regenerative Amplifiers
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...
