Generation of few-cycle terawatt light pulses using optical parametric chirped pulse amplification.
We demonstrate the generation of 9.8+/-0.3 fs laser pulses with a peak power exceeding one terawatt at 30 Hz repetition rate, using optical parametric chirped pulse amplification. The amplifier is pumped by 140 mJ, 60 ps pulses at 532 nm, and amplifies seed pulses from a Ti:Sapphire oscillator to 23 mJ/pulse, resulting in 10.5 mJ/pulse after compression while amplified fluorescence is kept belo...
متن کامل90 GW peak power few-cycle mid-infrared pulses from an optical parametric amplifier.
We demonstrate a compact 20 Hz repetition-rate mid-IR OPCPA system operating at a central wavelength of 3900 nm with the tail-to-tail spectrum extending over 600 nm and delivering 8 mJ pulses that are compressed to 83 fs (<7 optical cycles). Because of the long optical period (∼13 fs) and a high peak power, the system opens a range of unprecedented opportunities for tabletop ultrafast science a...
متن کاملNoncollinear Phase Matching in Optical Parametric Chirped-Pulse Amplification
Optical parametric chirped pulse amplication (OPCPA) is a method used to generate high-powered laser pulses. In this process, energy fiom a "pump" pulse is used to amplify a signal "seed" pulse. A computer program based on an analytical model was written and used to demonstrate the influence of noncollinearity, a condition in which the pump and seed are not parallel, and crystal tilt on the sig...
متن کاملOptical Parametric Amplification Techniques for the Generation of High-Energy Few-Optical-Cycles IR Pulses for Strong Field Applications
Over the last few decades, the investigation of ultrafast phenomena occurring in atoms, molecules and solid-state systems under a strong-field regime of light-matter interaction has attracted great attention. The increasing request for a suitable optical technology is significantly boosting the development of powerful ultrafast laser sources. In this framework, Optical Parametric Amplification ...
متن کاملModeling high-peak-power few-cycle field waveform generation by optical parametric amplification in the long-wavelength infrared.
Extended coupled-wave analysis of optical parametric chirped-pulse amplification (OPCPA) reveals regimes whereby high-peak-power few-cycle pulses can be generated in the long-wavelength infrared (LWIR) spectral range. Broadband OPCPA in suitable nonlinear crystals pumped at around 2 μm and seeded either through the signal or the idler input is shown to enable the generation of high-power field ...
